Notification does not works

[TobiasTao]

Describe the bug
I tried two methods to send a notification:

1. via js

  showNotification(): void {
    const notification = new Notification('Hi there!');
  }

result: nothing happened: no notificaions and no errors

2. via rust:

event::listen(String::from("notification"), move |msg| {
        println!("got notification with message '{:?}'", msg);
        let res = Notification::new()
          .title("New message")
          .body("You've got a new message.")
          .show();

        match res {
          Err(e) => {},
          Ok(_) => println!("notification success")
        }
      })

app crashed with errors:

Did you request permissions to show notifications first? For example:

window.Notification.requestPermission()

[TobiasTao]

i tried it:

    Notification.requestPermission().then(status => {
      console.log(status); 
      const n = new Notification('title', {body: 'notification body'}); 
    });

but permission is 'denied':

how can i change it?

[zicklag]

Oh, do you have notifications enabled in your tauri.conf.json?

[TobiasTao]

I have enabled all API features:

I have the same problem. The notification doesn't work in the osx build, but it works in dev mode.

@AlexanderShvaykin
I have the same problem. Will you consider repairing this problem? It works on MAC, but it doesn't work on windows.

Unfortunately we need better info to reproduce the error. Seems like it only happens on some specific setups.

[kmcluckie]

This is happening to me also:

thread 'main' panicked at 'failed to call RoInitialize: error -2147417850', C:\.....\winrt-0.4.0\src\rt\mod.rs:729:9

I am not a desktop developer, but my uneducated investigation shows this has to do with initialising the Window Runtime, and mod.rs specifies RO_INIT_MULTITHREADED. The error code returned leads me to search results with the error message "Cannot change thread mode after it is set". So perhaps we are trying to reinitialise WinRT in a multithreaded mode, whereas it was initialised as singlethreaded already?

This is absolutely uneducated tinkering, but I would like to assist to clear this up as it is preventing me moving forward. Any direction from the Rust and Windows experts is welcome.

[lucasfernog]

I have a fix for this, I'll push it tonight.

When working with Push.js(https://pushjs.org/docs/introduction), the desktop notification will pop up but then in less than one second the window (both dev and prod) will crash.
