Comment:

 Okay, I have a dirty fix for this. Originally I figured we might as well
 do some planned refactors in this code while i was digging around in it,
 but those are much more invasive than I initially thought (the effects
 reach out to a few lib/ things, and more importantly, all the way out to
 bin/auth), I'll create a separate ticket for those (since i have most of
 that code already).

 This fix just makes sure that some values in answer_message are set, even
 though, for immediate errors, answer_message isn't actually used (the
 error response is directly rendered, but the rest of the resolver code
 assumes it does use answer_message, which caused the problem)
