🐛 [CLOUD_FIRESTORE] The service is currently unavailable.

[ghost]

Bug report

I'm try to use Firestore with Flutter Deskop (MacOS). But I'm getting always this error since my first try for a month.

[cloud_firestore/unavailable] The service is currently unavailable. This is a most likely a transient condition and may be corrected by retrying with a backoff.

Steps to reproduce

1. Created iosApp on Firebase and downloaded GoogleService-Info.plist file to macos project
2. AppBundle (in Runner.xcworkspace) is edited like on Firebase
3. Creted a collection and document on Firebase (myCollection/myDocument)
   (All steps on https://firebase.flutter.dev/docs/installation/macos)

Expected behavior

I wish to get name value from myDocument on Firebase

Hi @kaiserleka,
Can you create a fresh Flutter project and try below steps to see if it works ?

1. Setup a default Flutter project.
2. Add cloud_firestore and firebase_core to pubspec.yaml.
3. Create a project in Firestore. Create a collection. Create a single simple document in that collection.
4. Follow the instructions at https://firebase.flutter.dev/docs/installation/macos to install GoogleService-Info.plist file.
5. Initialize Firebase, following the FutureBuilder / Stateful example here: https://firebase.flutter.dev/docs/overview/#initializing-flutterfire
6. Add import 'package:cloud_firestore/cloud_firestore.dart';
7. Use your code sample provided above.
8. Run app and see if you still get same error ?

Thanks.

Hi @kaiserleka,
Can you create a fresh Flutter project and try below steps to see if it works ?

1. Setup a default Flutter project.

I have created a new Flutter project and enabled desktop support.

2. Add cloud_firestore and firebase_core to pubspec.yaml.

I have added both of that packages to pubspec.yaml

3. Create a project in Firestore. Create a collection. Create a single simple document in that collection.

I have created new Firestore project and created a collection named "testCollection"

4. Follow the instructions at https://firebase.flutter.dev/docs/installation/macos to install GoogleService-Info.plist file.

4.1 I have name my named my project

5. Initialize Firebase, following the FutureBuilder / Stateful example here:
   https://firebase.flutter.dev/docs/overview/#initializing-flutterfire

I have located that stateful example onto my main.dart. When I run it, it works

import 'package:flutter/material.dart';
// Import the firebase_core plugin
import 'package:firebase_core/firebase_core.dart';
import 'package:cloud_firestore/cloud_firestore.dart';

void main() {
  runApp(MaterialApp(home: App()));
}

class App extends StatefulWidget {
  _AppState createState() => _AppState();
}

class _AppState extends State<App> {
  // Set default `_initialized` and `_error` state to false
  bool _initialized = false;
  bool _error = false;

  // Define an async function to initialize FlutterFire
  void initializeFlutterFire() async {
    try {
      // Wait for Firebase to initialize and set `_initialized` state to true
      await Firebase.initializeApp().catchError((e) => print(e));
      setState(() {
        _initialized = true;
      });
    } catch (e) {
      // Set `_error` state to true if Firebase initialization fails
      print(e);
      setState(() {
        _error = true;
      });
    }
  }

  @override
  void initState() {
    initializeFlutterFire();
    super.initState();
  }

  @override
  Widget build(BuildContext context) {
    // Show error message if initialization failed
    if (_error) {
      print("_error : " + _error.toString());
      return Scaffold(
        body: Center(
          child: Text("Error: " + _error.toString()),
        ),
      );
    }

    // Show a loader until FlutterFire is initialized
    if (!_initialized) {
      return Scaffold(
        body: Center(
          child: CircularProgressIndicator(),
        ),
      );
    }
    return Scaffold(
      body: Center(
        child: Text("initialized"),
      ),
    );
  }
}

6. Add import 'package:cloud_firestore/cloud_firestore.dart';

I have added

7. Use your code sample provided above.

I have updated my code with firestore. Event I run Firebase.initializeApp(), it says "[core/no-app] No Firebase App '[DEFAULT]' has been created - call Firebase.initializeApp()"

import 'package:flutter/material.dart';
// Import the firebase_core plugin
import 'package:firebase_core/firebase_core.dart';
import 'package:cloud_firestore/cloud_firestore.dart';

void main() {
  runApp(MaterialApp(home: App()));
}

class App extends StatefulWidget {
  _AppState createState() => _AppState();
}

class _AppState extends State<App> {
  // Set default `_initialized` and `_error` state to false
  bool _initialized = false;
  bool _error = false;

  // Define an async function to initialize FlutterFire
  void initializeFlutterFire() async {
    try {
      // Wait for Firebase to initialize and set `_initialized` state to true
      await Firebase.initializeApp().catchError((e) => print(e));
      setState(() {
        _initialized = true;
      });
    } catch (e) {
      // Set `_error` state to true if Firebase initialization fails
      print(e);
      setState(() {
        _error = true;
      });
    }
  }

  @override
  void initState() {
    initializeFlutterFire();
    super.initState();
  }

  @override
  Widget build(BuildContext context) {
    // Show error message if initialization failed
    if (_error) {
      print("_error : " + _error.toString());
      return Scaffold(
        body: Center(
          child: Text("Error: " + _error.toString()),
        ),
      );
    }

    // Show a loader until FlutterFire is initialized
    if (!_initialized) {
      return Scaffold(
        body: Center(
          child: CircularProgressIndicator(),
        ),
      );
    }
    CollectionReference users =
        FirebaseFirestore.instance.collection('testCollection');
    return Scaffold(
      body: Center(
        child: Column(children: [
          Text("initialized"),
          Divider(),
          FutureBuilder<DocumentSnapshot>(
            future: users.doc("testDocument").get(),
            builder: (BuildContext context,
                AsyncSnapshot<DocumentSnapshot> snapshot) {
              if (snapshot.hasError) {
                print(snapshot.error.toString());
                return Text(snapshot.error.toString());
              }

              if (snapshot.connectionState == ConnectionState.done) {
                Map<String, dynamic> data = snapshot.data.data();
                return Text("Value: ${data['testField']}");
              }

              return Text("loading");
            },
          ),
        ]),
      ),
    );
  }
}

@kaiserleka,
Since firebase_core is the first and foremost important plugin after migration, initializing it is the first step to integrate firebase in your app. You can do that inside main() method itself, like below and see if it works for you.

void main() async {
  await Firebase.initializeApp();
  runApp(MyApp());
}

I'm getting : [core/not-initialized] Firebase has not been initialized. Please check the documentation for your platform.

bool isFirebaseReady = true;
void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await Firebase.initializeApp().catchError((e) {
    isFirebaseReady = false;
    print(e);
  });
  runApp(MaterialApp(home: App()));
}

Why I can't find any complete Flutter Firestore Macos project :(

[evanpon]

@kaiserleka - is your macos app in App Sandbox mode, and if so, did you add the com.apple.security.network.client entitlement?

I have also added this to entitlement files but still getting : [core/not-initialized] Firebase has not been initialized. Please check the documentation for your platform.

<key>com.apple.security.network.client</key>
<true/>

[evanpon]

My apologies, my comment wasn't very helpful without additional context. I don't know why you are getting the Firebase has not been initialized. error. I tried looking through your code, but I'm pretty new to Flutter and wasn't able to spot the issue.

My comment about the entitlement was to address your original problem, which was that you were getting an error message about cloud_firestore being unavailable.

That said, here is a main.dart file that successfully connects to Firestore for me on macos. I imagine all the other setup (pubspec, entitlements, etc) is now similar to mine so I won't paste it all.

        future: Firebase.initializeApp(),
        builder: (context, snapshot) {
          // Check for errors
          if (snapshot.hasError) {
            return const Text("Error", textDirection: TextDirection.ltr);
          }
          if (snapshot.connectionState == ConnectionState.done) {
            return MaterialApp(
              title: 'Flutter Demo',
              theme: ThemeData(

              home: MyHomePage(title: 'Flutter Demo Home Page'),
            );
          }
          return const Text("Loading", textDirection: TextDirection.ltr);
        });
  }
}

Could you share those files and related macos files just in case? Your dart code still giving that error @evanpon

[evanpon]

I created a new project from scratch, and made the (I think) minimum changes to make it work for Firestore. You can see the repo and look at the commits here: https://github.com/evanpon/macos_firestore. The one piece it doesn't have is the GoogleService-Info.plist file, since you'll need that from your own project.

[tgpsantos]

I'm also looking for a solution to this error. In my case I get it only when my device (Android) is offline. I'm not able to create new documents when offline due to this exception.

[findnizam]

Anyone found a solution for this. I have been trying for the last two days and couldnt find a solution.

[shinriyo]

[cloud_firestore/unavailable] The service is currently unavailable. This is a most likely a transient condition and may be corrected by retrying with a backoff.

it happened recently.
google products always have annoying bugs

[StephanCassel]

Same here.

Used to work like a charm but not anymore.

await Firebase.initializeApp();

await authService.signinAnonymously(); // OK

var documentSnapshot = await FirebaseFirestore.instance.collection('user').doc(deviceId).get(); // HANG

after 10 seconds or so:
The service is currently unavailable. This is a most likely a transient condition and may be corrected by retrying with a backoff.

[loic-hamdi]

Same error on iOS 14 physical device. Anyone found a solution ?

[mtcliatt]

Same issue on macos with firebase_core 0.5.1 and cloud_firestore 0.14.2

[rakeshparveen5]

Facing the same issue.
Currently using these firebase packages :
firebase_core: ^1.10.6
firebase_analytics: ^9.0.4
firebase_auth: ^3.3.4
cloud_firestore: ^3.1.5
firebase_storage: ^10.2.4
firebase_messaging: ^11.2.4

[docaohuynh]

In my case I forgot to check exist

final doc = await docRef.doc(docId).get();
// got error here
data = doc.data();

fixed by add check exits

final doc = await docRef.doc(docId).get();
if (doc.exists) {
     data = doc.data();
}

[emerson-mec]

Emulator version 31.3.11 solved my problem.

[mateendev3]

FirebaseException ([cloud_firestore/unavailable] The service is currently unavailable. This is a most likely a transient condition and may be corrected by retrying with a backoff.)
Facing this issue when App is installed for the first time. If I close it and reopen it it work. Why??

[Vilmir]

I am re-facing this issue now with my project, after more than a year with 0 unavailable error.
It started reappearing again on Dec 8th. I implemented a retry mechanism for each Firebase call with a 60sec timeout, and the calls to doc(String).get() all fail all the time while the wireless connection works perfectly fine. The snapshots on Firestore documents work on the other end, except if I call .last on them, they then never complete.

I was about to release my first beta to our test users, I am now totally blocked with no idea on what I can do.
I have of course tried the classics: restarting my router, my mac, the phones, cleaning everything, I added a FirebaseFirestore.instance.disableNetwork/enableNetwork in my retry mechanism etc.

Am I the only one in that case?

[Vilmir]

If a Firestore dev reads this, I rolled back my project to the last beta release that was stable, and I got rid of the unavailable errors by using these pub versions:

Stable

cloud_firestore: ^3.4.3

Unstable

cloud_firestore: ^4.2.0

It's a pretty large range, and I do not have time to test all intermediate versions, but the problem appeared between 3.4.3 and 4.2.0

Good news, it's not a server issue, it is definitely a client library issue. Either in the Flutter adapter layer or the native library.

[Vilmir]

Correction, after one more hour of intensive testing, the cloud_firestore/unavailable is back on doc(String).get() calls with cloud_firestore 3.4.3

No idea what is happening. We need your support Google engineers!

[Vilmir]

After a day of testing and playing with versions, I could get back to a stable situation by using google-services 4.3.13 and cloud_firestore 4.2.0 instead of the latest 4.3.14
I could not find any official recommendation on the version to use with firebase, until I tried, desperately, regenerating a new google-services.json from the console, and there the install steps mention using 4.3.13
It would help to have the recommended google-services version mentioned on the pub pages of the packages.

I have done about 8 hours of testing, so the problem could reappear.

[Guuuud]

Hello mate, is this method applies to iOS as well? Could you please tell where to set the google services, I didn't find the place change the version

[loolooii]

This is happening to me on iOS simulator using cloud_firestore 4.3.1

[bbence84]

Same issue here. :( But also happens on 4.4.3 :(

[Guuuud]

Same issue mate, mine is also 4.4.3, I've been debugging it for nearly a week and find no clues to deal with it

[cammoore54]

I've been grappling with this over the last few days and the repeatable behaviour I've been able to produce is this:

• Occurs when trying to get a specific document from a collection where that document doesn't exist
• Only occurs when offline
• Occurs on Android and IOS

For example, the below DOESN'T raise the error:

var collectionRef = FirebaseFirestore.instance.collection('tags');
var tags = await collectionRef.get(GetOptions(source: source)));

However, the below DOES raise the error (only when offline):

var collectionRef = FirebaseFirestore.instance.collection('tags');
var doc = await collectionRef.doc(id).get(GetOptions(source: source)); //where id doesn't exist for this collection

For both of the above I have confirmed that the correct data is stored in the cache when offline

What is also strange is making this call online first, then going offline doesn't cause the error but if the device is offline the first time the call is made raises the error.

This is an example of how I combatted the error:

    try {
      // Private class that stores online state
      Source source =
          NetworkStatus().deviceIsOnline ? Source.serverAndCache : Source.cache;
      var collectionRef = FirebaseFirestore.instance.collection('tags');
      var doc = await collectionRef.doc(id).get(GetOptions(source: source));
      return doc.exists;
    } on FirebaseException catch (e) {
      print('Firebase error ' + e.code.toString());
      return false;
    } catch (e) {
      throw e;
    }

in release builds, this is happening with low internet speeds. The fix you mentioned won't work there as deviceIsOnline will still return true with low internet speed.

Now that this is fully understood (thanks @cammoore54) I've raised an actual issue so we can get this addressed as it straight up breaks apps:

#10887

What worked for me

1. Delete ios folder
2. Terminal -> flutter create . // This will recreate the ios folder for you
3. Terminal -> flutter clean && flutter pub get && flutterfire configure
4. Select your project, configure and setup once again.
5. Build project again

Only issue is we have a complex data in there which we can't just delete

[AyeshaIftikhar]

I am still having this issue. Has anyone solved it yet?

[gvsakhil]

I am still facing this issue... When firestore throws an error they are not clear like for which document error is being thrown or which line of code... Debugging is very difficult...

[AyeshaIftikhar]

Check your code if you are trying to fetch and update the same document at a same time. Thanks and Regards, Ayesha Iftikhar

I don't have anything like that in my code. I read document only through listener. Update is part of separate function...

Are you using google ml kit in your code? They do cause this kind of issue in the app.

[100Hamza]

Are you using google ml kit in your code?

so do you have any idea how we can solve this problem ?

I was able to resolve this issue by getting off of the spark plan and then redoing my database collection, thankfully I didn't have data to restore but this worked out for me.

[GeorgeKouk]

Thanks, will give this a shot

[Sudo-4L0N3]

Thanks, will give this a shot

Does it work on you, mate?

Hey mate, I think I found the unavailability error was due to low connectivity but I wasn't able to recreate it when I downgraded my simulator network speed. I did not delete my db or anything.

I encountered the same error yesterday :

[cloud_firestore/unavailable] The service is currently unavailable. This is most likely a transient condition and may be resolved by retrying with a backoff.

This issue persisted for around 3 to 4 hours, and the cause turned out to be quite simple: I had just enabled and created my Firestore Database service a few minutes before attempting to add data to it.

In the past, I had always used the default database name, but this time I named it something different, for example, 'example'.

If you choose a custom database name, you need to specify the database ID or name in the instance like this:

FirebaseFirestore.instanceFor(app: Firebase.app(), databaseId: 'example');

I hope this helps anyone facing the same issue ! ☀️
