Server error in Craft after redirect from Google IDP

[rostockahoi]

Hi there, I have an error with Google SSO.

What happens

• click on login in Craft
• redirect to Google login
• login
• redirect back to Craft
• 500 server error in Craft

Fix

I am able to fix the error and everything works just fine by putting the following line above User.php:145: $user->email = $user->usename;

I feel like I am missing some configuration, do I?

Exception output

• Translation: "E-Mail darf nicht leer sein." => "Email must not be empty."

Do you have email mapping configured on the IdP Edit page?

I have one instance mapped from the Google side like this:

Then from the Craft side like this:

Works like a charm, thank's a lot for that fast response.
