CircleCI not sending Content-Type in API responses without specific Accept request header

Ideally Content-Type would be included even if not specified in the request headers.

This was for https://circleci.com/api/v1.1/me

This is the intended behavior for now as documented here: https://circleci.com/docs/api/v1-reference/#accept-header

Nicely formatted JSON is still application/json. It doesn’t contradict the statement you posted. TIOLI.
