When saving user profile using PHP 7.4, we get
Notice: Trying to access array offset on value of type null in function SchemaHasPartBase::actionValidation() (rivi 242 tiedostossa /srv/sanoma/lauta/build-develop-122/sites/all/modules/contrib/schema_metatag/src/SchemaActionTrait.php).
PHP 7.4 is less permissive on accessing NULL type.

It's likely this issue predates Contrib.social: some issue and comment data are missing.
Can you please test the current 7.x-1.x dev snapshot and let us know if the problem still happens? The code was heavily rewritten by KarenS in 2020 and so the actionValidation() method no longer exists. Thank you.
