POST Request route

[andodeki]

I am have this endpoint a post request which does not respond even the the print statement i have in the function
It this even the way a post request fn is created

async fn create_user(
    StateRef(state): StateRef<'_, AppState>,
    ExtensionRef(user_data): ExtensionRef<'_, CreateUserRequest>,
) -> String {
    println!("Testing Create User API");
    let id = state
        .user_db
        .next_id
        .fetch_add(1, std::sync::atomic::Ordering::SeqCst)
        .to_string();
    let _new_user = User {
        id,
        name: user_data.name.clone(),
        email: user_data.email.clone(),
        created_at: chrono::Local::now().to_rfc3339(),
    };   
}

below is the routes of said request

let app = App::new()
        .with_state(state)
        .at("/test-post", post(handler_service(async || "POST works\n")))
        .at("/users/create", post(handler_service(create_user)));

the test-post works though

I suggest you add a self contained example to demonstrate the issue. As I cant reproduce it with your snippet.
If I have to take a guess you would want to make sure if the response is an error (4xx or 5xx) or no response at all.
