Mind to apply https://github.com/nextcloud/server/issues/19010#issuecomment-576683752 and share the stack trace?

[nooblag]

PS if I do 19010 how do I share stack trace?

[kesselb]

You should see another line in your log.

[nooblag]

Okay thanks, I'll be gutsy and give it a go changing core files to help fix this! First timer... so fingers crossed. 🤞

Changes made now, standby for logs. I'll update as soon as I notice one.

This is what I've got now:

Should be fixed by: https://github.com/nextcloud/groupfolders/pull/942

Unfortunately there is no release of groupfolders app with this fix yet.

[john-2000]

Hi
I have a similar issue but I am unsure if there is an appropriate bug report already, my log is getting flooded with the below message.
Do I need to open a bug report for this separately?

Trying to access array offset on value of type null at /var/www/nextcloud/lib/private/Files/Cache/Scanner.php#418

Nextcloud 19.0.1
PHP 7.4
Ubuntu 20.04

[kesselb]

Closing in favour of https://github.com/nextcloud/groupfolders/issues/907 (which is also closed. fix is merged, next step is a release, already pinged the right people).
