Could you check the Nextcloud log again? There should definitely be an error logged for a 500 http status.
Ok, I finally got:

It looks like it wants some permission it doesn't have.
ls -la Readme.md
-rw-rw----+ 1 nextcloud nextcloud 16 May 6 13:02 Readme.md
The php-fpm instance is running as the user nextcloud and it has write permissions for the file.
I dunno what created this Readme.md. It gets automatically created by some app. I haven't found out how to turn it of.
However deleting the Readme.md and then recreating it, fixes it again.
This has something to do with the nextcloud delete permission.
It looks like it is unable to delete the preview of that given file. Could you check if the permissions within your data/appdata_[instanceid]/previews directory are correctly set so that the nextcloud user can delete files?
Text file previews? Isn't it faster to just read the first 200 bytes?
find appdata_*/preview -name "*.md" -type f -ls
I only see image files in the preview directory.
Hi, I have the same issue, but the error in the logs seems strange and this is a md file, which I created to test it. Because of this error the collectives app is also not working. Also strange is, that I get an 409 Error beforehand the 500 Error. nc text logs.log
Thanks!
I also wanted to look into the Collectives App, but it isn't functional at all, probably because of the underlying issue here ...
Looks like an incompatibility with the backup app from the log:
"message": "OC\\DB\\QueryBuilder\\QueryBuilder::__construct(): Argument #3 ($logger) must be of type Psr\\Log\\LoggerInterface, OC\\Log given, called in /var/www/html/custom_apps/backup/vendor/artificial-owl/my-small-php-tools/lib/Db/Nextcloud/nc23/NC23ExtendedQueryBuilder.php on line 74 in file '/var/www/html/lib/private/DB/QueryBuilder/QueryBuilder.php' line 86",
Could you check if disabling the backup app fixes that?
Looks related: https://github.com/nextcloud/backup/issues/294 https://github.com/nextcloud/backup/issues/293
Hi, so. Deaktivating the Backup App solved the Problem! Amazing! :) Also the collectives app works again.
Thanks for the workaround!
@cryptomilk Maybe you could also check that, then I'd close this here as the original issue is already tracked in the backup app.
I don't use the Backup app and I have nothing logged in the logs. The questions remains why the one file didn't have the DELETE permissions and so Text failed but I was able to just delete the file.
Maybe to recap then, the file that failed to delete was not a markdown file but the preview image that was generated previously which will get cleaned up on a document save.
One thing you could check would be if the webserver has the correct permissions on all files and folders in your data directory, especially within the appdata_[instanceid]/preview and its subdirectories.
The permissions are correct as I also run nextcloud-fix-permission --complete which is part of our RPM. It looked more like a database flag as nextcloud seems to have more file permissions in the database.
I'm running into the issue again and I have a guess now.
I think the problem occurs if you have a conflict between the current and the saved version. The server return 403 in this case. If I resolve the conflict and click on the button to use the saved version I get the error 500 next.

It would be useful if the message would actually tell you the path it doesn't have a delete permission for and if this is a nextcloud permission or POSIX path permission.
@cryptomilk did you find a solution to this problem? Do you still encounter it?
It sems like PreviewWatcher->postWrite() that is triggered by the postWrite event tries to delete the previews but lacks delete permissions.
Could you check the permissions in data/appdata_*/preview/*/*/*/*/*/*/*/${fileId}, ${fileId} being the file ID of the markdown file you're editing (you should see it as openfile get parameter in the URL)?
I'll close this due to lack of information. Feel free to reopen with further information if you still encounter this bug.
