I'm getting this error whenever I save my script include for the first time. It gets inserted on the second try.

Please try below solution: 

In the UI Action script,  there is a function "gsftSubmit()".  pass "null" as a third parameter. This will fix the issue. (as reverting back to OOB, disabled some customizations).

Please refer to the below URL for reference. Also, refer the below KB article:
