Originally assigned to: @FrostBreker on GitHub.

For a week or two now I've been getting error messages whenever I try running codes using this script e.g.

package main

import (
    "fmt"
    "log"

    spotifyprivateapi "github.com/FrostBreker/spotify-private-api"
)

func main() {
    client := spotifyprivateapi.NewClient(spotifyprivateapi.Client{
        Debug: true,
    })

    // Replace with a valid Spotify track ID
    track, err := client.FetchTrack("7sFMOSnRBa6td4lZa1oiTI")
    if err != nil {
        log.Fatal(err)
    }

    // Print the album name
    albumName := track.Album.Name

    // Print the primary artist name
    artistName := "Unknown Artist"
    if len(track.Artists) > 0 {
        artistName = track.Artists[0].Name
    }

    fmt.Println("Artist:", artistName)
    fmt.Println("Album:", albumName)
}

returns
