I just made an edit to my Form Output and am now seeing the following error:
This error indicates our server has not had the time to re-execute the newly-added Form Output. This will automatically re-execute to the new Form Output within a few minutes of the edit being made, therefore the error will be moved to 'complete' very soon.
Additionally, you do have the option to select the re-execute button beside that Destination here:
Though the server will automatically do this, you do have this option available to speed up the process.
