Firebase call returns http post failure in addition to error message when registering a user that already exists

[fearonf]

The code calling Firebase is:

var email = vm.username;
var password = vm.password;

                firebase.auth().createUserWithEmailAndPassword(email, password).then(function(){
                    console.log("user created in firebase");

                    //Create a new user in the secur database too, for user profile

                     $http.post('/api/users/register',user).then(function(result) {
                         console.log("User profile added to secur database too")
                         console.log(result);
                         vm.message = 'Successful registration, please login.';

                     }).catch(function(error) {
                         console.log(error);

                     })

                }) .catch(function (error) {
                    // Handle Errors here.
                    var errorCode = error.code;
                    var errorMessage = error.message;

             
                    vm.error = errorMessage;
                    vm.message='';
                    console.log(vm.error);

                });

Input: a@b.c password: aaaaaa
When error returned is 'the email address is badly formatted' , just the message is returned in the console log:
The email address is badly formatted.

Input: a@gmail.com password: aaaaaa
when error returned is 'The email address is already in use by another account.' the following is logged in the console:
POST https://www.googleapis.com/identitytoolkit/v3/relyingparty/signupNewUser?key=*********************** 400 ()
register-controller.js:67 The email address is already in use by another account.

Closing since nobody has provided info on which sample this happens in. If someone has more evidence of this issue, feel free to comment and I can reopen.
