I am the developer that left the stack trace on returned exceptions. This is part of my Presidential Innovation Fellowship project at NASA. Yes, we work with the Chief Data Scientist, who is a wonderful and brilliant guy. Yes, we work with state and local governments, too - where "we" is civic tech in the US government (18F, USDS, PIF, among others). I'd love help on these APIs. First step: submit issues on the docs (github.com/nasa/api-docs).
