Can't run Web playback sdk promise rejection

[vladimir9307]

Hi, I decided to give the web playback sdk a try.
I pasted the code provided here
https://developer.spotify.com/documentation/web-playback-sdk/quick-start/
I added my token. 

When I open the html in chrome during the loading I get 

(promise rejection)
After that whatever I do - changing the song in my player, lowering the volume doesn't trigger the `player_state_changed` event.

I am using Chrome, tried it in Mozilla and Edge. Always the same result. 
I decided to give it a try in a localhost env but the same happens.

Looking forward to any suggestion, thanks in advance.

EDIT: 
This is the message which I get in the promise rejections : "unsupported keysystem or supportedconfigurations". 

I managed to make it work - i didn't switch my player to the newly created.
