4 years ago I forgot: My RasPi 3 runs Node.js v10.16.3 and NPM 6.10.3
and here is my test-webpage that tests different ways of calling Sonos-http: The only one that works is "openpage", but it opens a new tab and steals focus, so it's not usable to me.

I try to play MP3-files from my 2019 latest Updates RasPi-Sonos-to-HTTP-Server. The commands come from a local javascript webpage running on Chrome (it's for an escape room, events happening there, but also music and atmoshere playing).
I use:
<script> const openasync = async (website) => { const response = await fetch(website); } </script>to send the http-request.openasync('http://192.168.178.101:5005/sonos1/clip/sail.mp3');let's my Sonos play the song. And this works.Also with other calls like HTTP.XHR.request or new image=(website);or open.window(website); it works, though the latter has limitations.
If I call another clip/song.mp3 while playing ... this works too. 1st song stops and 2nd plays immediately. But if I call a third while still playing everything breaks down. Nothing works anymore and I have to reset my webpage. Sonos starts playing my Clips repeatedly or in wild order. Chrome seems to wait for somthing. And sometimes I get errors like: net::ERR_EMPTY_RESPONSE
What am I missing?
I just would like it to send a command with javascript to the Sonos so it immediately stops doing what it just did and starts playing the new clip.mp3-File or pauses. Files are all there. I can play them one after another. But as soon as the interfere something seems to break?
Please help?
