Expected behavior

The unshare action should complete without errors.

Nextcloud Signing status

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.

[tflidd]

I can reproduce this error on an independent setup (FreeBSD, nginx, php 8.2.29, default user). I get a different line number:

"message": "Undefined constant OCP\Share::SHARE_TYPE_USER in file '/usr/local/www/nextcloud-test/apps/maps/lib/Hooks/FileHooks.php' line 149"

app version (appinfo/info.xml) -> 1.6.0

Error goes away when I disable the maps app.

[Hawolex]

Se the same in my production "Nextcloud Hub 25 Autumn" Official Docker

Can delete file not just the sharing.

I had to disable maps as it prevented me from logging into my instance with the admin account. At least one other user was not affected.
When executing php occ user:info admin I got:

Any News , anybody tried this workaround ?
"Possible fix: replace OCP\Share::SHARE_TYPE_USER with \OCP\Share\IShare::TYPE_USER in FileHooks.php."

[gvelim]

I have made the change based on the above recommendation and I don't get the error anymore with the map app activated. Maps appear to work fine too.

is this a proper fix or just a hack though ?

        public function postUnShare($params) {
                //logger('maps')->debug("Hook postUnShare");
                if ($params['shareType'] === Share::TYPE_USER) {

                }
        }

        public function preUnShare($params) {
                //logger('maps')->debug("Hook preUnShare");
                if ($params['shareType'] === Share::TYPE_USER) {
                }
        }

Tried it out myself (replacing SHARE_TYPE_USER with TYPE_USER in FileHooks.php as shown above), however it doesn't work: I'm still unable to unshare files. I have to deactivate Maps to do so.

Sad, I was confident that the workaround will work, you can hardly make a mistake when implementing it...

Replacing Share::SHARE_TYPE_USER with Share\IShare::TYPE_USER in these 2 cases as described in the bug report fixed the issue for me.

Horray, that indeed did the trick for me as well. Thank you very much indeed!

P.S.: This should be rolled out officially in a new version asap.

Confirming that un-sharing does not work in Nextcloud Hub 25 Autumn (32.0.1):
