Getting Invalid JSON error in my BF Helper

I have an onFormRequest script for a Form. I’m trying to investigate some issues I’m having.

I looked in the BF helper and just noticed I had many of these records that indicated there’s some sort of error.

TypeError: null is not an object (evaluating 'obj[i].constructor')

I’m new at all this.

I’m guessing it’s telling me that somewhere there’s bad JSON being set? Is there anything I can do to pinpoint what’s causing this error?
