Bug description

Since a silent update of the Docker image I pulled yesterday, the following is logged whenever I try to share or unshare a file:

[no app in context] Error: Undefined constant OCP\Share::SHARE_TYPE_USER in file '/var/www/html/custom_apps/maps/lib/Hooks/FileHooks.php' line 154

	from ***REMOVED SENSITIVE VALUE*** at Oct 15, 2025, 2:13:11 PM

I hit the error "Error: Undefined constant OCP\\Share::SHARE_TYPE_USER at /var/www/html/custom_apps/maps/lib/Hooks/FileHooks.php#154" when DAVx5 calender sync and fresh login from Android device failed - both is back to normal after disabling maps app.
maps seem incompatible with NC32 now nextcloud/maps#1467

[starze]

The incompatible maps app (nextcloud/maps#1467) led to a broken files_sharing app, which in turn caused errors in QOwnNotes during startup. See pbek/QOwnNotes#3411 for details.

Deactivating maps ultimately resolved the issue, but I was wondering whether the Nextcloud server could somehow better encapsulate apps so that a broken maps app, for example, would not affect QOwnNotes.

[prairietree]

I am running into the same error but only when trying to remove a share. I am using the files app to share and or remove share, but when I try to delete a share it says:

And I get this error in the logs:
Exception Undefined constant OCP\Share::SHARE_TYPE_USER in file '/var/www/html/custom_apps/maps/lib/Hooks/FileHooks.php' line 154

I disabled the Maps app and was able to remove one share. I am not sure how the maps app would be breaking sharing in the Files app but that seems to be the case.
