Last year I created a C#/WPF application with an embedded Spotify Web Player SDK. It has worked fine, as far as I am aware, for the last 400+ days. However, recently it has stopped working. As far as I can estimate, it stopped working around 15 days ago.
This link is very much related to the problem I am having (it is the foundation of what has been working for the last 400+ days):
https://github.com/spotify/web-playback-sdk/issues/34#issuecomment-409838775
When I run that code I get the following error in my console:
SCRIPT5009: 'Promise' is undefined.
index.js (345,429)
I try the code with both of the suggestions here:
https://github.com/spotify/web-playback-sdk/issues/34#issue-328445209
Are others experiencing the same issue I am reporting? Can anybody offer some guidance how to get this to work in Internet Explorer 11?
Here is the code (if it can be made to work then it will very likely solve my issue):
<!DOCTYPE html>
<html>
<head>
<title>Spotify Web Player</title>
<script src='https://cdn.jsdelivr.net/npm/es6-promise@4/dist/es6-promise.min.js'></script>
<script>ES6Promise.polyfill();</script>
</head>
<body>
<h1>Spotify Web Player</h1>
<div id='log'>
</div>
<script src='https://sdk.scdn.co/spotify-player.js'></script>
<script>
window.onSpotifyWebPlaybackSDKReady = function() {
function log(message) {
document.getElementById('log').innerHTML += '<pre>' + message + '</pre>';
}
var token = '{accessToken}';
var player = new Spotify.Player({
name: 'Spotify Web Player',
getOAuthToken: function(cb) { cb(token); }
});
// Error handling
player.addListener('initialization_error', function(error) { log('initialization_error: ' + JSON.stringify(error)); });
player.addListener('authentication_error', function(error) { log('authentication_error: ' + JSON.stringify(error)); });
player.addListener('account_error', function(error) { log('account_error: ' + JSON.stringify(error)); });
player.addListener('playback_error', function(error) { log('playback_error: ' + JSON.stringify(error)); });
// Playback status updates
player.addListener('player_state_changed', function(state) { log('player_state_changed: ' + JSON.stringify(state)); });
// Ready
player.addListener('ready', function(result) {
log('player ready: ' + JSON.stringify(result));
});
// Not Ready
player.addListener('not_ready', function(result) {
log('player not ready: ' + JSON.stringify(result));
});
// Connect to the player!
player.connect();
};
</script>
</body>
