createOAuth2Token not letting login user
account.createOAuth2Token is returning the following error message: { "message": "A user with the same id, email, or phone already exists in this project.", "code": 409, "type": "user_already_exists", "version": "1.5.7" }
TL;DR
The developer is having trouble logging in a user due to an error message stating a user with the same id, email, or phone already exists in the project.
Solution: Check for existing users with the same credentials or use a different method to create the OAuth2 token.
