FirebaseUser.getIdToken throw FirebaseException

[Vladimir Samoylov]

Hi everyone! 
We faced with error
Calling FirebaseUser.getIdToken(forceRefresh = true) throws exception for anonymous user

com.google.firebase.FirebaseException: An internal error has occurred. [ Quota exceeded for quota metric 'Token exchange' and limit 'Token exchange per minute' of service 'securetoken.googleapis.com' for consumer 'project_number:<number hidden>'. ] at com.google.android.gms.internal.firebase-auth-api.zztt.zza(com.google.firebase:firebase-auth@@20.0.3:4) at com.google.android.gms.internal.firebase-auth-api.zzvb.zza(com.google.firebase:firebase-auth@@20.0.3:9) at com.google.android.gms.internal.firebase-auth-api.zzvc.zzk(com.google.firebase:firebase-auth@@20.0.3:1) at com.google.android.gms.internal.firebase-auth-api.zzuz.zzh(com.google.firebase:firebase-auth@@20.0.3:25) at com.google.android.gms.internal.firebase-auth-api.zzub.zza(com.google.firebase:firebase-auth@@20.0.3:20) at com.google.android.gms.internal.firebase-auth-api.zzb.onTransact(com.google.firebase:firebase-auth@@20.0.3:3) at android.os.Binder.execTransactInternal(Binder.java:1184) at android.os.Binder.execTransact(Binder.java:1143)
Who can help to figure out can we increase the limit?

You need to make less requests. Is there any reason you need forceRefresh = true in each call? This is likely unnecessary and removing it should free up some quota.

I had the same error; solved it by:

1. Going to https://console.developers.google.com/apis/credentials,
2. Clicking on the API key
3. Enabling the "Token Service API", along with "Identity Toolkit API"
