When dragging a card from one column to another I get the following error:
Unhandled Exception ("InvalidArgumentException") Argument 1 passed to array_fuse() must be of the type array, null given, called in /srv/www/phabricator/src/applications/herald/adapter/HeraldAdapter.php on line 441 and defined
Things that may be part of the cause:
Tasks in that project are in a separate "space".
Edit permissions exclude the public, and only cover project members.
Anything else in our installation is unmodified, we use the version directly from the official git sources.
If more information is required, feel free to ask.
