media_player does not work in node-red

[zstonez]

I have a node red flow, to play some radiostreams from the radio browser to my sonos boxes. Now i want to do this to my pc.
When i use the media player card in my dashboard, i can choose the music-stream and it works. I can play/pause the stream and toggle volume.
My next step was to switch den media_player entitiy in my node red flow from sonos to browser_mod. But that doesnt work. i can use tts and use play/pause with node red, thats okay.
But i cant send the radio-browser-stream witrh its media content id like this

{
"media_content_id": "https://www.ndr.de/resources/metadaten/audio/m3u/ndr1radiomv_hgw.m3u",
"media_content_type": "music"
}

and this is my test flow:
