Web Playback SDK

[vikrant1]

I am working on side project which is spotify clone so i want to play song in my project so how can i use web playback sdk in angular project.

I follow https://developer.spotify.com/documentation/web-playback-sdk/tutorials/getting-started and used same code in index.html but getting below error while building application
uncaught AnthemError: onSpotifyWebPlaybackSDKReady is not defined
at new t (spotify-player.js:18:9580)
at a (spotify-player.js:18:10186)

window.onSpotifyWebPlaybackSDKReady = () => {

console.log("Spotify Web Playback SDK is ready.");

};

this function is needed to work it properly
