There is a section in my JSON payload that looks like the screenshot below. It contains the reps ID that I need to grab. I am unable to grab the ID indicated (joseph.winters) because the middle section is also uniquely identified (wc:joseph.winters@quickt...)

So if I send over different payload of data, lets say with another agent (mick.jones) with different data, it errors out my zap because my mapping cannot be found. like this:

any thoughts on how I can get around this?
