As discussed on the last WG meetup it makes sense to define some common error properties like:
code
,category
, etc. I think such initiative should be lead by public API owners and required broader discussion.However, I think we could make this process more painless by proactively preventing possible name clashes.
For example, if a future version of spec will defines
code
as a string it can break some public API that use integers for error codes.Another alternative would be to recommend prefixing additional fields with
x-
(e.g.x-code
) but I think it's better to reuseextensions
from response object.
