Nextcloud Logs

Exception: Undefined constant OCP\Share::SHARE_TYPE_USER in file '/var/www/html/custom_apps/maps/lib/Hooks/FileHooks.php' line 154

Browser Console

Additional info

Sharing works, but unsharing is blocked by the exception.
It seems related to the removal of the constant OCP\Share::SHARE_TYPE_USER in recent Nextcloud versions.
Possible fix: replace OCP\Share::SHARE_TYPE_USER with \OCP\Share\IShare::TYPE_USER in FileHooks.php.
