Description of the Change

Much like our last PR, this one is a hotfix to an issue found in prod.

Additionally, this PR adds a try/catch around the main logic call, so in the event the whole process crashes due to a typo or invalid syntax, we actually get a proper error returned, rather than invalid gateway.
