Summary
RFC7807 defines a "problem detail" as
The spec is somewhat irrelevant, but due to the extended content type Rails does not recognize
application/problem+json
as JSON (particularly when parsing test Response bodies). This PR proposes adding it as an additional recognized Mime subtype forapplication/json
Other Information
The largest counterpoint I can think of is the previous addition and removal of
application/vnd.api+json
(see #23712). Unlikevnd.api+json
,problem_json
is an RFC-specific format that is universal - not vendor-specific - and native support would add lots of value to Rails API projects.
