Additional info

I know that there is already a solution for this problem
-> #31771
-> #29674

Was already implemented in my Nextcloud and doesn't help

[Ecmoechr]

Can anybody tell me, what is to be done? Do I have to install a patch, update the database? I am running with the newest nextcloud-version, but error still exists. Thank you!

[joshtrichards]

@samuelstein @belzebub40k @JappeHallunken Your reported matters fixed in #42427 / #42524 and will be released in the next NC28 point release (you're welcome to apply and test the contents of #42524 though - it's already been merged for release - if you don't wish to to wait). Unfortunately I don't think your situations are directly related to the original reporter's issue though.

[joshtrichards]

@sschwalbe I'm also confused about your original report because your config is from v26.0.1, but your log entry is from v24.0.1.1. The log entry also seems to be from a year prior to your original report. In addition #31771 wasn't merged until after your report - it was still a work in process and the code evolved further so your early testing may not be representative of the end product.

@sschwalbe & @Ecmoechr - Are either of you still experiencing this with newer versions of NC?

It's fixed for me in 28.0.2
