I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.

[prameshj]

Thanks for reporting.. we are working on a fix. Meanwhile can you confirm if this is happening for users that are logging in anonymously or using any other provider?

This could happen if the FirebaseUser did not have any provider info or user id associated with them. We will include additional logging along with the fix to help future debugging easier.

[MarjanaKarzek]

@DeuceTheCoder thanks for reporting the issue! I was just about to create an issue report for it myself.
@prameshj we are experiencing the same issue in version 22.1.1 even.
We are also unable to reproduce the issue but have noticed it happens on app start and might therefore be a bug within the initialisation of FirebaseApp.

[Vignesh-772]

@prameshj This is happening when user are logging in anonymously.

[argzdev]

Hi all, if others also encounter this issue, please do leave a thumbs up on the original author's post so we can track the severity of the issue. Thanks!

[prameshj]

@prameshj This is happening when user are logging in anonymously.

Are you seeing this for new users who are logging in anonymously? Or are these previously created users, which are now just reopening the app?

I am asking because this issue can happen only if there is no firebase info associated with the user json, which indicates a malformed representation of the user, that is in persistence.

[Vignesh-772]

@prameshj Not sure about when it is happening. We don't have stack trace for the origin.
This is how we implemented we will check getCurrentUser() if it is gives null then we are calling signInAnonymously().

[MarjanaKarzek]

We are not calling signInAnonymously() in our app

[vashisthg]

I am also getting a lot of crashes due to this in our production app in play store.

[prameshj]

Thanks for the responses. We hope to make the fix available in a following release soon.

As mentioned above, the issue should only happen if the persisted user info was in a malformed state, need not necessarily because of anonymous auth. If you do find a specific repro, please add details here (about the user sign in method, how long the account info was persisted for). This does not block the release of the fix, we are doing that in parallel. Thanks!

@prameshj @NhienLam Any update on the fix for this? By when will this be rolled out?

[prameshj]

We will be including the fix in the upcoming release (should happen within the next 2 weeks). We will update here once the release notes are published.

[argzdev]

Hi folks, a new version of Firebase Auth has been released. That said could you try the latest version 22.1.2 and see if the issue still persists? Thanks!

[google-oss-bot]

Hey @DeuceTheCoder. We need more information to resolve this issue but there hasn't been an update in 5 weekdays. I'm marking the issue as stale and if there are no new updates in the next 5 days I will close it automatically.

If you have more information that will help us get to the bottom of this, just add a comment!

[argzdev]

HI folks, since we're no longer receiving any updates related to this. I'll close this for now. Feel free to let me know if we have to reopen this. Thanks!

[AdHrithik]

Is this issue solved in flutter package as well? If not, when can we expect it?

[argzdev]

Hi @AdHrithik, checking the latest release notes in the flutterfire repo, it doesn't seem to be included. Please reach out to the flutterfire team to get updates regarding their planned release date with the fix.
