Bug description

Hello,

Today I upgraded Nextcloud after New Release 30 was available. I See this error on log reader:

DriverException An exception occurred while executing a query: SQLSTATE[42000]: Syntax error or access violation: 1055 Expression #1 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'nextcloud.cr.id' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by
Error while running background job OCA\DAV\BackgroundJob\EventReminderJob (id: 12, arguments: null)

I have never seen this error in all these years that I have used Nextcloud.

I can of course remove this Mysql Variable but i don't know if the Problem it's Mysql Server or a Nextcloud Bug.

thank you
