DELETE request fails with "Body cannot be empty when content-type is set to 'application/json'" about openapi-typescript HOT 1 OPEN

The error message Body cannot be empty when content-type is set to 'application/json' is unique to your endpoint, so I don’t think there’s a good default that can be changed here (for most endpoints, Content-Type: application/json helps endpoints return the correct response back as a default).

Also you can unset that default header for all endpoints with:

createClient({ headers: { 'Content-Type': null } });

But yes if you wanted to do something more complex such as send application/json for all endpoints by default, but omit that header for DELETE requests, then that’d probably have to be solved with upcoming middleware support (#1122)
