My cursory guess is this is some kind of authentication error.

Maybe it's worth pointing out that I disregarded the note in the readme about setting up the .zendesk2.yaml file and instead just opted to pass all the authentication params into the client initializer, not sure if that matters.

Scratch that, I was over-thinking it. The constant is simply out of scope here:

@nozpheratu yanked 1.7.3 and released 1.7.4 with the USER_AGENT fix
