IntoResponses #[response(...)] attributes only allows status

[Piscolero]

If using the IntoResponses derive macro, you cannot specify other response attributes besides status, although documentation says otherwise.

Example:

use utoipa::IntoResponses;

#[derive(IntoResponses)]
enum MyResponses {
    // this works
    #[response(status = NOT_FOUND)]
    #[allow(unused)]
    NotFound,

    // adding other attributes to response except status doesn't build
    // Error: expected identifier
    #[response(status = UNAUTHORIZED, example = json!({error: "not authorized"}))]
    NotAuthorized,
}

fn main() {}

Compilation fails with:

error: expected identifier
  --> src/main.rs:11:37
   |
11 |     #[response(status = UNAUTHORIZED, example = json!({error: "not authorized"}))]
   |                                     ^

try adding a status code.

try adding a status code.

If you mean using status = 401 instead of status = UNAUTHORIZED, I already tried that without success.

I can confirm I have the exact same problem. In addition to example I also tried content_type (cf #660). But the same problem occurs.

Only status works.

Try removing the comma, this is actually a bug in the latest release: 3.3.0 that is fixed here: 16bec9d.
