JSONObject["relatedTableID"] not found code:500[] What does this mean?

JSONObject["relatedTableID"] not found code:500[] 

Does anyone have any idea what this means and how to fix it?

Also what's the deal with the insanely vague error messages when publishing. Incredibly unhelpful and frustrating to figure out.

Can you provide your XLSX?

I have seen a few JSONObject errors, but they were all from submitting to an already published survey.

This could potentially be a few things, so being able to inspect the XLSX and attempt to publish locally would help greatly.
