Cannot read properties of undefined reading "default" error on Windows when running project locally

[Vette1123]

I followed your steps regarding how to run the project, but i keep getting this error

[Dhravya]

I remember getting that once. Can you try deleting node_modules, installing dependencies again, and running the web app in apps/web?

cd apps/web
bun run dev

[Vette1123]

same issue

[leestreetnet]

Getting same error, tried deleting node_modules to no avail.

I believe it's from the const usr = await auth() line in app/page.tsx - I logged usr and it returns a null value.

Windows OS

[Dhravya]

hmm, that should be fine tbh, @Vette1123 what operating system are you on?

[Vette1123]

Windows 11

[jfortez]

same

[Dhravya]

maybe I'm unable to reproduce because I'm running on a Mac.

I'm pretty sure this is a bun-related issue. can someone try using npm / pnpm ?

[Dhravya]

Also, does anyone know why this is the case for windows? #11

I haven't got this error, i tried running the script, also manual setup, i only faced the issue mentioned here, haven't got the account id issue

but thanks for your response, will try different package manager and let you know

[leestreetnet]

ran npm run dev in both root and apps/web directory, still same issue

[Dhravya]

Can you share the apps/web/wrangler.toml file?

[Vette1123]

@Dhravya switched to pnpm and still same error

[Dhravya]

@Vette1123 did you also install dependencies using pnpm?

[Vette1123]

@Vette1123 did you also install dependencies using pnpm?

yea,

[whistle-dev]

I get this straight from setup and bun run dev

[paulls597]

I'm lost I don't even know what I'm looking at! I'm just on this site so I can look like I'm doing something important in front of my girlfriend.

[Dhravya]

paul, tell your girlfriend that i said hi

to others: this is a bug in wrangler - fixing!

[Vette1123]

[Vette1123]

[ioabhishek]

i tried setting up next project outside without turbo and it worked fine but when cloning the same repo inside turbo getting this issue

[ioabhishek]

Hey did you got any fix for this

[Vette1123]

getting the same error

i tried setting up next project outside without turbo and it worked fine but when cloning the same repo inside turbo getting this issue

with turborepo its not working

i solved default error by deleting

export const runtime = 'edge' from page.tsx file

but i was still getting prepare issue as the picture i attached above (it was something wrong with d1, cloudlfrare, wrangler), i swithced to turso and its working fine now, at least until cloudflare errors get solved for windows

[ioabhishek]

but if we will remove this export const runtime = 'edge' then nextauth adapter will not work i think so

[Vette1123]

but if we will remove this export const runtime = 'edge' then nextauth adapter will not work i think so

it will, give it a try.

auth.js supports both edge and node runtime

[ioabhishek]

not able to figure it out, working fine in a plain next js app but cloning the same in turborepo is giving error

[codingforfoodllc]

getting this error as well.

[jivjen]

Yup same error for me as well on windows. Any possible workaround for this yet?

[jivjen]

@codingforfoodllc @ioabhishek @leestreetnet @Vette1123 @paulls597 @jfortez @leestreetnet @Dhravya
After some intense trial and error I have found a fix for this issue.
Go to app/web/package.json and make it
"dev": "next dev --turbo"
And this resolves the D1 connectivity issue and the inital error.

Later I faced some error related to the auth call and stuff made inside page.tsx

⨯ Error: headers was called outside a request scope

and that is coz next auth 5.0.0-beta.19 is not really in good terms with --turbo apparently lol (nextauthjs/next-auth#11076)
So I specified the version like this "next-auth": "5.0.0-beta.18" instead of "next-auth": "^5.0.0-beta.18" and now everything works like a charm.
Also reminder to ditch windows asap! xD

[leestreetnet]

@jivjen thanks for --turbo fix!

Hitting the headers error now and the 5.0.0-beta18 change didn't fix for me unfortunately. I'll spend some time testing too.

[jivjen]

@leestreetnet Try deleting node_modules and package-lock.json from the directories and do a fresh install. Hopefully that should resolve it.

[leestreetnet]

@jivjen this worked - appreciate you

Anyone working on Windows and running into these issues, @jivjen solution worked for me.

[Aunchers]

@jivjen
You are amazing.
