Here's a picture of the error I'm getting for reference.

In both of the above, I've removed the controller name as it's my actual last name. You can see at initial startup (20:57:34) the error is present, as well as for any subsequent synchs (20:59:01). At 20:59:06 I clicked the "Run Script" button, and at the next sync (21:00:07) there are no errors.
