Confirmed. Interesting that on my local instance trying to edit/save 13027 I have another error

403 RuntimeException

Invalid response from GitHub

@b2z do you test against the CMS Repo?

Than the error makes sense as you don't have access to the CMS Repo using github.

exception: JTracker\Github\Exception\GithubException: Issue not editable by b2z in ROOT/src/JTracker/Github/GithubObject.php:49

That shouldn't be blocking his tests though because that Exception should be caught and trigger a bot trying to perform the action on his behalf.

Yes but if i have understand @b2z he is esting on his own repo against the cms

Yeap I ma trying to edit :)
