Every Univents error is an application/problem+json body: type, status, title, detail and instance are always present, plus errors: [{ field, message }] when request fields are at fault. A problem's type is {API_URL}/problems/{slug}, which the API itself serves as documentation. Branch on the slug at the end of type, not on title or detail. The members listed below a problem are its own, on top of the standard ones.
