E/Volley: [2672] BasicNetwork.performRequest: Unexpected response code 400 for https://www.googleapis.com/identitytoolkit/v3/relyingparty/signupNewUser?alt=proto&key=api-key

Error occurs when creating a new user

Steps to reproduce:

What happened? How can we make the problem occur?
testing on an Android device， but no error when using an emulator
This could be a description, log/console output, etc.

Relevant Code:

// TODO(you): code here to reproduce the problem

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

@kisanzxy does this happen every time you create a new user? What are the steps to reproduce this?

[kisanzxy]

@samstern
This happens only on the Android phone. And yes, it happens every time I create a new user on the android device. However, it works fine on the emulator. I use the sample code to test on a device and it happened.

[samtstern]

@kisanzxy can you please provide the code that causes this issue? And what is the phone model? What version of Google Play services (settings --> apps --> Google Play services) is running on the phone?

[kisanzxy]

@samtstern
Google play services version 16.0.89

And for the code. Could I email you or invite you as a collaborator?

[samtstern]

@kisanzxy please just provide a small snippet of code here where the problem occurs, we can't look at or debug your whole project.

[kisanzxy]

@samtstern This is where the bug might be; it always goes into the else branch and prints out
" CreateAccount Authentication failed." and the Firebase console didn't update
But we can create new user successfully everytime when testing on the emulator

And there is a snippet of the Gradle file

project level

    dependencies {
        classpath 'com.android.tools.build:gradle:3.3.2'
        classpath 'com.google.gms:google-services:4.0.1'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }

private void createAccount(String email, String password) {
        Log.d(TAG, "createAccount:" + email);
        if (!validateForm()) {
            return;
        }

        // [START create_user_with_email]
        mAuth.createUserWithEmailAndPassword(email, password)
                .addOnCompleteListener(getActivity(), new OnCompleteListener<AuthResult>() {

                        if (task.isSuccessful()) {
                            // Sign in success, update UI with the signed-in user's information
                            Log.d(TAG, "createUserWithEmail:success");

                            Toast.makeText(getActivity(), "CreateAccount Success.",
                                    Toast.LENGTH_SHORT).show();
                            FirebaseUser user = mAuth.getCurrentUser();

                        } else {
                            // If sign in fails, display a message to the user.
                            Log.w(TAG, "createUserWithEmail:failure", task.getException());
                            Toast.makeText(getActivity(), "CreateAccount Authentication failed.",
                                    Toast.LENGTH_SHORT).show();

                        }

                    }

                });
        // [END create_user_with_email]
    }

@malcolmdeck any idea what might cause a simple createUserWithEmailAndPassword to return a 400 error? The device has latest GmsCore (16.0.089) and the code works on an emulator, which is the opposite of the problem people normally have.

[malcolmdeck]

+Leonardo Siracusa <[email protected]> This looks new to me. Leo, any ideas?

What exception is it failing with?

[kisanzxy]

@samtstern
HI, I feel so sorry to report this bug. The only reason that we cannot create a new user is that when typing in the email, there is a single space added to the end. So the auth failed because of the bad format error after we look into the full error message. However, the error message only printed out half part " CreateAccount Authentication failed.". It's really hard to notice this tiny " " at the end of the email string.

@kisanzxy thanks for telling us!
@lsirac can we maybe have the backend trim some inputs?
