"TypeError: Failed to fetch" in "Validate single-spa application" step

[dly75]

Following steps in playground to test an Angular app, I've got TypeError: Failed to fetch in "Validate single-spa application".

What am I doing wrong ?

myApp starts on port 4200 :

Not sure it is what i should expect... ?

And in playground i have a blank screen :

Right ?

Thank you for your help

I've also had the same issue. Did you managed to fix it?

I just re-tried this morning with a brand new application.
Doing nothing more, and nothing different from my first try, I can now verify my app until step 2 :

Looking at https://github.com/systemjs/systemjs/blob/main/docs/errors.md#8, I don't understand what i am expected to do.

After reading a lot, I can only confirm this : http://localhost:4200/main.js showing the bundle (see the 2nd screenshot in my first post) is correct.

In my mind, playground instructions / site may be out of date...
