Gateway exposes internal errors

Code reviewDistributed systemsSenior–Staff~25 min

Review this TypeScript gateway handler that calls an internal payments microservice and relays its result to the public client.

Which questions mattered is sealed until you submit. Telling you now would just be handing over the edge cases.
