I got this just now, after I edited a run sheet and the only change I made was editing the service comments... could that be it?

Doesnt seem to be

I experienced an issue like this one today, in the context of a bug that was preventing JethroServicePlanner.onsubmit to run before the form submitted. The heading_text elements are added in to the request by this function.
So I suspect the original errors are some similar situation, where the form is 'natively' submitting without the onSubmit function running.

Despite not having tracked down the original trigger, I'm fairly confident this change will make this one go away.
