Channel Send Error Mishandling

[drer17]

I have this command,

#[tauri::command]
fn async subscribe_to_logs(app: State< '_, Mutex<App>>, on_event: Channel<String>) {
    let guard = app.lock().unwrap().get_receiver();
    while let Some(msg) = guard.recv().await {
        if on_event.send(msg).is_err() {
            warn!("Navigated away from logging.");
            break;
        }
    }
}

I am expecting the on_event.send to return an Err when the event handler is garbage collected on the JS side by the user navigated away from the page. Instead, I am getting this error on the front end.

TypeError: window['_' + 815124574] is not a function. (In 'window['_' + 815124574]({ message: response, id: 37 })', 'window['_' + 815124574]' is undefined)

As the Channels are evaluating JS under the hood, is it possible that the error is not properly handled?

If, I am misusing channels and there is an easier way to achieve this, I would love to learn.
