How can I return empty InternalServerError? Without any message/body?

[danechitoaie]

I currently have something like this:

#[derive(ApiResponse)]
enum DeleteResponse {
    /// **No Content** - Encrypted secret deleted
    #[oai(status = 204)]
    NoContent,

    /// **Internal Server Error** - Failed to delete encrypted secret due to some unexpected internal error
    #[oai(status = 500)]
    InternalServerError,
}

    /// Delete data
    #[oai(path = "/api/data/:key", method = "delete", tag = ApiTags::Data)]
    async fn delete(&self, Data(redis_connection): Data<&ConnectionManager>, Path(key): Path<Uuid>) -> DeleteResponse {
        let mut redis_connection: ConnectionManager = redis_connection.clone();
        let redis_key: String = key.to_string();

        let del_result = redis_connection.del::<String, ()>(redis_key).await;
        match del_result {
            Ok(_) => DeleteResponse::NoContent,
            Err(_) => DeleteResponse::InternalServerError,
        }
    }

This makes DeleteResponse::InternalServerError be visible in JSON spec and Swagger UI docs. Is there any way I can omit that?
Or how to modify the handler to return different InternalServerError (not from the DeleteResponse enum) that has only status code and no body?
