Tauri rust functions hanging

[cerulean dagger]

When I register a handler rust side and create a simple function, and then await window.TAURI.invoke(“my_cool_function”) it hangs.

Lets see my_cool_function

Most likely the issue is in the function code and not in Tauri itself

[cerulean dagger]

#[tauri::command]
fn start_discord_rpc() -> String {
  println!("[RUST] DiscordRPC requested to be started by JS.");
  println!("[RUST] DiscordRPC connected to Client.");
  return "T".to_string();
}

        .invoke_handler(tauri::generate_handler![start_discord_rpc])

console.log(await window.__TAURI__.invoke("start_discord_rpc"));

what the

Do you have withGlobalTauri enabled?
And can I see your full main() function?

[cerulean dagger]

fn main() {
    tauri::Builder::default()

        .plugin(tauri_plugin_log::Builder::default().targets([
        Target::new(TargetKind::Stdout),
        Target::new(TargetKind::Webview),
        ]).build())
        .invoke_handler(tauri::generate_handler![start_discord_rpc])
        .invoke_handler(tauri::generate_handler![set_discord_rpc])
        .run(tauri::generate_context!())
        .expect("error while running tauri application");
}

  "build": {
    "beforeDevCommand": "yarn dev",
    "beforeBuildCommand": "yarn build",
    "devPath": "http://localhost:5173",
    "distDir": "../dist",
    "withGlobalTauri": true
  },

This is wrong. You should only use invoke_handler once

        .invoke_handler(tauri::generate_handler![start_discord_rpc, set_discord_rpc])
