FLUTTER FIREBASE_AUTH MISSING IDENTIFIER CUSTOM TOKEN REGISTER

[meihdimtg]

I have a problem, registering a user with an email password and a custom token, except that this changed 1 month ago, no one can register on my application anymore, but on the web side it works. However, the authToken Web and the authToken Flutter are the same returned by the API and it works on the website and on the app I have an error that does not go away even if I have updated my packages.

The api uses the json file for the web and the app so normally if it works on the web side it should work on the app side

However, the Firebase keys work correctly, the json files are in the root, I have an internal error, MISSING IDENTIFIER however the token returned by my api works for the NEXT JS version which has the same token as that of the app except that via the application and the flutter firebase_auth package this no longer works.

I/flutter (24065): Error during authentication: [firebase_auth/unknown] An internal error has occurred. [MISSING_IDENTIFIER]

The user is created correctly on firebase auth and on my app except that there is an auth error for my users, and when connecting with this same token then the user cannot access the application this creates an Nullity error
