Since upgrading to NC 18.0.1 I get an error message popup (top right corner) when renaming/moving files saying "Cannot rename/move ". When reloading the page the new filename is correctly renamed/moved.
In the log i see something like this:
Undefined variable: node at /var/www/nextcloud/apps/workflow_script/lib/Operation.php#203
Error: Call to a member function getPath() on null
