How to pass async data to the component?

[mikwee]

I wrote a function that uses fetch() to fetch the necessary information for the audio stream, and put it in an object per the example in the readme. It works when I just call it, but I'm not sure how to pass this object to the component. This:

<script>
 let song = getSong("dMBcOobWD4k");
</script>

<Aplayer audio={song}/>

Does not work. I get a white screen, and this error pops up in the console:

Uncaught TypeError: m2 is undefined
    update svelte-aplayer.es.js:1
    F svelte-aplayer.es.js:1
    svelte_aplayer_es_default svelte-aplayer.es.js:1
    create_fragment App.svelte:26
    init Component.js:148

    ProxyComponent proxy.js:242
    Proxy<App> proxy.js:349
    <anonymous> main.js:4
svelte-aplayer.es.js:1:29740

I've tried many different thing, incl. async and await. Do you know how to do such a thing?
Thanks.
