Bug description

I'm running Nextcloud 30.0.6. I received a notification that an update to the mail application existed so I selected the update option. I received the following error message. Is this a problem or more of an erroneous notification? Since the column being checked already existed I suspect it's probably OK. The mail application appears to be running OK and it states its version 4.2.0 which appears to be the latest. Just wanted to check.

Update to 30.0.6
