I’ve just signed up to comment on the (new) NC 31.
It has a major bug in it, which is causing lots of other bugs:
My previews don’t work anymore in hub 10:
XImg.vue:95 Failed to load XImg Error fetching single preview: {“message”:“Could not resolve OCP\ILogger! Class can not be instantiated”}
Also, this same error of OCP\Logger class not being instantiated causes lots of other (small) bugs throughout the application and is filling up my logs like no tomorrow.
I couldn’t find anything related to this specific bug online. Does Nextcloud know about this? where can I find a solution or discuss this ?
Forgive me if this is not the right section but unfortunately I have no time to dive and dig into forums and sections at this moment, and am desperately looking for a solution and/or waiting for a update to fix this as soon as possible.
These “small” bugs like no image previews is already pushing my users to go back to big tech services instead which destroys the whole goal of setting up nextcloud ( for me personally ).
Logs full of this same error :
"
Error no app in context
QueryException
Could not resolve OCP\ILogger! Class can not be instantiated "
Which is only happening in this hub 10 version for me.
Not sure for your code, if that is more specifically from an app, you can find the corresponding repos in apps.nextcloud.com in the description box of the app.
That might def. be the case since I force installed/enabled apps which I was using in the previous version and not work in this new version.
The error might even be totally unrelated in this case.
It will take me some time to individually enable/disable some of the force-enabled apps to see which one is causing the Logger class error.
I’m still clueless as to what is causing the problem ( no previews of images inside “Memory” and “Talk” conversations, but I do see low quality previews of all my photos in the “photos” app.
Do these apps use different preview creators ? ( like Imaginary, imagick, etc ) ? if yes, That might give me a clue where this problem is coming from but I could not find anything useful in the official documentation regarding this.
I’m using Nextcloud AIO ( Hub 10 - 31.0.0)
On docker, using WSL 2 Ubuntu 22.04 running on windows 11
I had a previous AIO installation using desktop docker, and in that instance the preview generated with no problems.
I don’t think Docker Desktop is the problem here but who knows.
I will try to find some time later to post most if not all the information needed for debugging. I understand that it’s close to impossible to find out what is causing this weird bug without more information from my side
No I don’t and I all my apps are updated. a day or 2 ago I received an update for the “Memories” app and was excited that this might finally solve my problems, but unforuntately it didn’t help much.
I don’t have any documentserver_community app enabled, so can’t be that.
Below some logs I get when I try to generate previews:

I’ve found the culprit in the most unexpected place.
I went and disabled most of the apps, and started re-enabling them one by one, looking at “memories” and " talk" app ( reloading them ) and see if preview will re-generate.
I disabled and re-enabled about 20 apps, but the most unexpected one was the cause of my preview generation misery:
Activities for shared file downloads
Version 1.17.0
I still have no idea how in the world this would affect preview generation but now it works. I have disabled/enabled this app about 3 times to double check, and yes. everytime this is turned on, I see no image preview inside Talk conversations or “Memories” app. as soon as I disable this app, reload the page, I see the previews and I also stop getting the weird Logger class error. Hope this can help anybody who is pulling their hair out trying to solve this weird bug.
That’s not all that surprising since that app (files_downloadactivity) hasn’t been published for v31 yet.
Presumably it’s force enabled in your environment, which bypasses all compatibility checks whenever you upgrade Nextcloud Server, leading to breakage like this.
I receive similar Error errors in my fresh Nextcloud Turnkey installation (vers. 31.0.2) on Proxmox LXC.
Looks like they occur every time a user open a file dialog
AND it doesn’t matter if it’s through an app (from Android or IOS) or if the web interface is used.
At this moment NO additional APPs are installed.
It’s pretty easy to replicate and a few slightly different error messages happening in a row, e.g. like:
[no app in context] Fehler: Could not resolve OCP\ILogger! Class can not be instantiated
PROPFIND /remote.php/dav/files/admin/

Please post an app list (occ app:list). I know of no default apps that still have this deprecated code in-place today. Maybe an app from one of the app bundles?
In my case, the app that produced this error was the Ransomware protection app. I installed it a long time ago. After uninstalling the error message went away.
had the same error message looping like hell, going deeper into the details of the message revealed that RansomwareProtection app was the culprit. disabling did remove that.
For now i can live without it, but i would like to reenable it at some point…
that’s what helped me.
