Existing https://github.com/firebase/flutterfire/issues/12449 was closed by the bot for no reason. The question on which OS the the IOS emulator is running was answered. (MacOS...)

[xkhangsama]

Same problem here

[deffs]

This is the same issue that I was referencing in this thread - https://github.com/firebase/flutterfire/issues/11581. I have a MWCE that is causing a crash on my Mac running iOS simulators and physical devices. I made a sample Microsoft tenant and added a user to it. I then created a user with the same email address on Firebase Auth using email/password. If you want access to the Firebase project I am testing this with I can add emails.

Here is the code (credentials for the sample account are included within): ios_fb_auth_crash.zip

This is the crash stack:

@russellwheatley this is the full issue repro

[ohhyungkwon]

Same here. It crashes at FirebaseAuthHostApiCodecWriter:writeValue and the value is not supported object type. The value is FIROAuthCredential instance. I guess we should hand over Pigeon thing instead of FIROAuthCredential.

Hey 👋 Found the issue, it's actually an error that is not properly parsed. You can see the full error here:

flutter: [firebase_auth/sign-in-failed] An account already exists with the same email address but different sign-in credentials. Sign in using a provider associated with this email address.

I've opened a fix. You should maybe use linkWithProvider

[deffs]

Thanks @Lyokone , @TarekkMA is there an estimated date or version number in which this will be released so I can upgrade to the package version with this fix?

[Lyokone]

You can use the latest version right away if you want using FlutterFire CLI:

dart pub global activate flutterfire_cli 1.0.1-dev.1 --overwrite
flutterfire install git:feat/12920

Otherwise our next scheduled release is next Tuesday.

[deffs]

Thanks for the pro-tip. I was able to test it and the error is now returning as expected without crashing. 🙌
