magento2 – {“exception”:”[object] (Magento\Framework\Validator\Exception(code: 0): One or more input exceptions have occurred

I’m getting the following issue since today, i’m not able to find out what is going on. It was all working fine for the past few months, and no files was modified recently. What could be the problem? ( Unfortunately, the support from the extension provider is expired, i’m trying to resolve the problem myself.)

checked: cron jobs are running fine.

checked: ticket.php was not modified.

checked: mysql is running

error from exception log
