Auth V9 Error on Chrome Android when Offline

[REQUIRED] Describe your environment

Operating System version: Android 10
Browser version: Chrome 95.0.4638.74
Firebase SDK version: v9.4.1
Firebase Product: Auth

[REQUIRED] Describe the problem

EDITED

Error messages that appear on Chrome for Android:

GET https://apis.google.com/js/api.js?onload=__iframefcb993633 net::ERR_INTERNET_DISCONNECTED load_js.ts

Uncaught (in promise) FirebaseError: Firebase: Error (auth/internal-error). errors.ts:91
    at createErrorInternal (assert.ts:128)
    at _createError (assert.ts:83)
    at HTMLScriptElement.el.onerror (load_js.ts:32)

Steps to reproduce:

While online, go to a Auth-enabled PWA using Chrome on Android. Browse some pages. After that go offline. Reload/revisit previously visited pages. What I found was that Firebase stop working. I didn't experience this on desktop also before v9.

Relevant Code:

const auth = getAuth(app);

Thanks for reporting @nasgnat

Would you be able to provide more information?

You can follow the code snippet shown here to see what the error actually is.
You can also enable debug messages by using firestore.setLogLevel('debug'); (reference)

@ehsannas

Thank you for your input @ehsannas. I have edited the issue above.

Turns out it wasn't the Firestore that was the error. It was only affected by the real error, namely auth?

I can reproduce this. I think the problem is when using a mobile device, the load_js.ts file calls https://apis.google.com/js/api.js.

This https://apis.google.com/js/api.js seems to require internet to work, so when the device is offline, it throws an error and stops the code afterwards. In your case it is Firebase Auth.

@RaheutRahwana

Thx for the info @RaheutRahwana. Looks like I'll have to roll back to v8 again until this issue is resolved.

Update

I found the same problem in Stack Overflow. Although it is not clear which version of the sdk is used.

Thanks for filing this! The linked PR should fix the issue; it should be available in the next release or the one after!
