Hello!
I am currently working on a react.js application that is integrating with the MusicKit v3 library. I have followed the documentation to generate a JWT for MusicKit and add the library to my application.
Using my token I am able to successfully retrieve song information from the Apple Music API, but I am having trouble with authentication.
When I call music.authorize() and successfully go through the Apple sign in popup, I am receiving the following 403 error:
https://play.itunes.apple.com/WebObjects/MZPlay.woa/wa/webPlayerLogout 403 musickit.js:44 Uncaught (in promise) AUTHORIZATION_ERROR: Unauthorized
After stepping through the music kit API and login popup with breakpoints, I am seeing that the music user token is null, despite the login popup succeeding and returning a proper token/response:
{"isAppleMusicSubscriber":"true","musicUserToken":"Ak4ItOgRRRG2y6xgA/OeWQPK0RqPQ/esAJkRN0B/Ua/AWLT52tLhd2TfzMK6uhH+Nczvd7wjYDM1UewG/NledKtimwlrR+s5tdQPk/FG28zqhBqXZ12q6LC516w8ELZDwv5T61kV8xiJ1KSO1q4pGi01JO7SuPMtOqB/QsycYj+xNnrYUEwlP5tm/zxfg7bWmvuWMwfUruYR+A1U9FdXZsdIITVmxCjiHg8ro9xXRzl6Txhsag\u003d\u003d","cid":"REDACTED","itre":"REDACTED","supported":"REDACTED"}
I have tested my application with multiple Apple Music users who have paid subscriptions. All accounts are receiving this same error.
I have tried regenerating my JWT token multiple times following various guides. My latest attempt used the following node library and parameters:
var jwt = require('jsonwebtoken');
var fs = require('fs');
var privateKey = fs.readFileSync('./AuthKey_MYKEY.p8');
let now = new Date();
let nextMonth = new Date(now.getFullYear(), now.getMonth() + 1, now.getDate());
let nowEpoch = Math.round(now.getTime() / 1000); // number of seconds since Epoch, in UTC
let nextMonthEpoch = Math.round(nextMonth.getTime() / 1000); // number of seconds since Epoch, in UTC
var payload = {
iss: 'REDACTED', // TEAM ID
iat: nowEpoch,
exp: nextMonthEpoch
};
var options = {
algorithm: 'ES256',
header: {
alg: 'ES256',
kid: 'REDACTED' // KEY ID
}
};
jwt.sign(payload, privateKey, options, function(error, token) {
console.log(error);
console.log(token);
});
I have a valid App Identifier created with the MusicKit App Service enabled.
I am stuck! I have no other ideas on the possible root cause here. Is there something I am missing? I have a mobile app currently in Test Flight - does this app need to be released to the app store? I am out of guesses!
Any support here would be greatly appreciated!
Thank you for your time.
