Firebase Authentication by SignUp with Email and Password

Describe the problem

In the first times, Firebase Authentication with Email/Password takes more 8 seconds to complete request.

If I retry the second times, it's very fast, takes less than 1 second.

Problem, I use Blocking Cloud Function (beforeUserCreated) combine with Firebase Authentication, the API identitytoolkit (account:signup) returns Error Message "BLOCKING_FUNCTION_ERROR_RESPONSE : Cloud function deadline exceeded.", cause timeout 7 seconds as Blocking Function's document descriptioned, therefore do Sign Up in first times always return Error, (it's OK when do signup in the second times)

Please help me to resolve this issue.

Steps and code to reproduce issue

Client Signup and Link Credential Code

const credential = EmailAuthProvider.credential(this.email, password);
await linkWithCredential(prevUser, credential);`

Blocking Cloud Function Code

export const beforeCustomerCreated = beforeUserCreated((event) => {
  return {
    customClaims: {
      role: AppRole.Customer,
    },
  };
});

I'm using Firebase v9 and facing failure signing-in and I suspect it is due to delays since yesterday. Again, this code has been working fine for over years and all of sudden I can't authenticate users.

I believe my issue is related to yours however I'm going to open a new issue!

Hi @KpYeahStar, this might be a cold start issue: https://firebase.google.com/docs/functions/tips#min.

You can try invoking the function after deploying it to reduce the latency at login.

Hi, please re-check my issue description. I call direct to google API (identity toolkit) from client by SDK js, not by Cloud Function.
