When I first started using promises, I got thrown by the error "promise rejected". I assumed that the bug was due to how I had set up the plumbing for my promises.
In actual fact, it just means an exception was raised. If I had looked more
closely, I would have seen the root cause was an error Cannot read property
postCode of undefined inside the promise.
