My log is full of "DB Error #1054" error messages.

OS: Debian 10
PHP: 7.3
All PHP settings correct
I'm using SMTP & IMAP + Auto-Fetch through a corn job + API to create tickets.

The error appears when fetching mails and also when using the API to create tickets. I created one custom form input. Should I just add the column "notes" manually?

Full Backtrace:
[INSERT INTO ost_user__cdata SET notes='', user_id= 118 ON DUPLICATE KEY UPDATE notes=''] Unknown column 'notes' in 'field list'
