Facebook not working - error in log

[peteralewis]

Hi, I've connected Facebook plugin settings & in the developer app, but when I try to connect via a template it goes straight to the redirect URL (using incognito and not logged into Facebook) with the following error in web.log:

[error][yii\base\ErrorException:8] yii\base\ErrorException: Undefined index: sourceFormField in /xxxxxxxxxx/vendor/enupal/socializer/src/services/Providers.php:826

The User Field Mapping in Socializer settings shows: "Socializer will populate email, firstName and lastName into the User model by default" and doesn't allow the Email field to be mapped, so not sure why the error is occuring.

@peteralewis Do you have any User Field mapping? Just to confirm, you never see the Facebook login page on incognito? I'll try to recreate it.

Hi, only field mapping I have was the displayName to a text field for the user called nickname. That was the only (social) field I could map. Correct - I never saw Facebook.

Ah, just had a thought and have checked the character limit for the custom nickname field and the field limit is set to 40 characters - could that have an impact? Besides that it's just a Plain Text field.
