OCP\AutoloadNotAllowedException: Autoload path not allowed: globalstoragesservice.php in autoloader.php

Hello, i run Nextcloud inside official docker container

After adding Preview Generator app via Nextcloud interface i tried to run: docker exec nextcloud ./occ preview:generate-all -vvv It ends with an error that I have not been able to find online. I am looking for some guidance on this.

An unhandled exception has been thrown:

What version of Nextcloud are you running? Are you making use of the files_external app?

[BerentM]

Nextcloud is on version 25.0.2 ~No, i don't use files_external app, i checked that via Nextcloud GUI.~

While looking for tool to get list of all installed apps, i found another ./occ command that ends with similar error. docker exec nextcloud ./occ app:list

So there might be more general problem with my instance, that is not related to preview generator.

EDIT: i found file called files_external inside apps folder

docker exec nextcloud ls apps | grep exter
files_external

Something weird is going on with your instance or your file system. May I ask on which file system your instance (/var/www/html/) is stored?

It seems like all file names and paths are lower cased and that is breaking the autoloader. E.g. /var/www/html/apps/files_external/lib/service/globalstoragesservice.php should be /var/www/html/apps/files_external/lib/Service/GlobalStoragesService.php

I run Nextcloud on Raspbery Pi 4B with plugged external SSD disc. I mount it with fstab: UUID=B278-A8E7 /mnt/data exfat defaults,uid=1000,gid=1000,dmask=007 0 0 And then i additionaly run sudo bindfs -u 1000 -g 1000 /mnt/data/ /home/mateo/docker/nextcloud_data/ because i had issues with starting nextcloud, if it tried to store data in /mnt/data.

Maybe logger messes up with paths, they look legit on my instance

It's strange, but after renaming/deleting the apps/files_external folder, the occ commands started working 😄 Your first comment about files_external + this one directed me to this fix. I don't understand why it started to work, but it works for now.

[st3iny]

That is great to hear! I'll close the issue.

Got with the same issue. Seems like I ran docker on a case insensitive file system (MAC OS APFS), and the Preview Generator app cause the same trouble.
