Spotify plugin not working with Spotify API

[twaclaw]

Setup: Raspberry Pi 4, Spotify Plugin 4.0.3, and Volumio image (3.569).

The Spotify plugin works as intended if I use the Spotify (mobile) App to play music; however, if I use the Spotify API I get a 404 and the plugin crashes. My application uses the API to play music. I have to manually restart the plugin in Volumio and it starts with a new device_id each time.

For instance, if I use the endpoint https://api.spotify.com/v1/me/player/play with parameters

{
    "context_uri": "spotify:album:5ht7ItJgpBH7W6vJ5BqpPr"
}

I get a 404.

In the RPi I see this error.

volumio go-librespot[2583]: time="2023-12-06T21:53:07+01:00" level=error msg="failed unmarshalling dealer request payload" error="json: cannot unmarshal number into Go struct field RequestPayload.target_alias_id of type string" uri="hm://connect-state/v1/player/command"

The same API works if I use the device_id of my cellphone, and is working as well with other implementations of librespot (in different RPi packages and audiophile images).
