These seem to be some technical debts. I get log entries every cron run. System: Arch, PHP8, NC21.0.2. Formatted logs:

Same error here wrote in
nextcloud/server#25806 (comment)

[julian70400]

Is this only an error message or there is a real and concrete issue which could affect datas stored ? In other worlds, is this issue is dangerous or we can just ignore it safely ?
Got it since I migrate my Nextcloud from PHP 7.4 to PHP 8.0.11

"Group folders" + "Versions" produce homepage 3-5 sec open delay. With this error "unsupported operand types: int & array" in the log.
If you disable "Group folders" app or/and "Versions" app - your homepage opening delay will gone.

I have the same error code flooding my logs however I also cannot connect remotely to my nextcloud server now, error 522 times out. Locally via a workstation over a LAN my Nextcloud is functioning however the log this error code 1x a hour which seems to be a clue that something is triggering this issue each hour.

Error | core | TypeError: Unsupported operand types: int & array

Snap revert nextcloud
nextcloud reverted to 22.2.0snap1
Did not correct this issue nor restored my remote ability to connect to my nextcloud, still has error 522 timing out waiting for nextcloud to respond. Nextcloud is responding correctly via LAN to my workstation. I've tried restarting Nextcloud, reverting back to 22.2.0snap1 to no avail. Some 2 weeks I had to revert nextcloud due to a release issue. I didn't notice the error 522 timing out error until after the latest snap update and I'm wondering if that is also linked?

For those having this problem, can you check/try nextcloud/server#28385?
(for v22 only)

There is no way of testing in a production environment, since no update was pushed, right?

I believe this was fixed by #1725

You can apply the patch manually:

1. Download https://patch-diff.githubusercontent.com/raw/nextcloud/groupfolders/pull/ <the number>.diff
2. Go to app/groupfolders
3. patch -p1 < <the number>.diff

In case this breaks, you can revert this with:

patch -R -p1 < <the number>.diff

The diff number depends on your Nextcloud version: 1728 for stable20, 1727 for stable21, 1726 for stable22, 1725 for master
