V9 Auth additionalUserInfo missing from login results

[daveteu]

[REQUIRED] Describe your environment

• Operating System version: macos
• Browser version: chrome
• Firebase SDK version: 9.0.0-beta.6
• Firebase Product: auth

[REQUIRED] Describe the problem

The code below used to return user. additionalUserInfo, but now it's replaced with _tokenResponse.

This information contains additionalUserInfo.isNewUser which identifys new user registration. The information is now inside _tokenReponse, while user.additionalUserInfo is now undefined.

Is this permanent change or bug? I cannot find documentation on this.

Relevant Code:

const auth = getAuth(firebase);

const async loginGoogleCredentials (tokenId) => {
  const credential = GoogleAuthProvider.credential(tokenId)
  return await signInWithCredential(auth, credential).catch(function(error) {
    return(error)
};

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

you have to import the function getAdditionalUserInfo from firebase/auth to get the additionalUserInfo data

Hi @daveteu, thanks for the report. As mentioned by @MistaPidaus, you should first import the getAdditionalUserInfo to use it. I was able to get the details by using this snippet:

signInWithPopup(firebaseAuth, provider)
      .then((result) => {
        const details = getAdditionalUserInfo(result)
        console.log(result);
        console.log(details)
      })
      .catch((error) => {
        console.log(error);
      });

You can use this as a guide for your implementation.
