Any hints, how to fix this issue?

Same problem over here, did you already find a fix?

I have the same problem too. Have anybody fixed that problem?

I’m using an NC18 now and I’m having the same problem.

  • calendar.view.index

In my environment these will output an error every 5 minutes.
In my case, this error started with NC17.

I have the same problem. Did it blocked your installation or just printed a lot of logs for nothing ? Because now I can’t access my files throw Nextcloud anymore and each time I try it print one line of log.
I use Nextcloud 18.0.6
