Do you really expect that I can debug in a few minutes, a part of the software that I didn't build and have never seen before and have no knowledge of the external, third-party web service that code is reaching out to?

Dude, flippin' chill, take a walk, grab a drink, pop some popcorn and give me some time to figure out what the hell this code is doing so I can properly debug it!

You know what it turned out to be? Wrong test data used for the 3rd party service. So in essence... Nothing was wrong! Frickity frack!
