    Description

      I'm seeing this error when trying to create an assignment when the feedback_plugin_for_gradebook setting is set to a feedback plugin that has been uninstalled:

      Exception - Call to a member function is_visible() on null

      To reproduce:

      1. In admin settings, set the setting "assign | feedback_plugin_for_gradebook" to "File feedback"
      2. Go to "Manage assignment feedback plugins" in the admin menu and uninstall this plugin
      3. Go to a course and add an assignment - you should see the above error when you click save
