I'm trying to access the MusicKit API but it keeps returning a 401 unauthorized error. I can't figure this out. I have this code to generate a Developer Token:
const privateKey = fs.readFileSync("resources/AuthKey.p8").toString();
const teamId = "MYTEAMID";
const keyId = "MYKEYID";
const options = {
algorithm: "ES256",
expiresIn: "180d",
issuer: "MYTEAMID", // your 10-character Team ID, obtained from your developer account
header: {
alg: "ES256",
kid: "MYKEYID", // your MusicKit Key ID
},
};
return new Promise((resolve: any, reject: any) => {
jwt.sign({}, privateKey, options, (error, token) => {
if (error) {
return reject(error);
} else { // token created
return resolve(token);
}
});
});
This generates a successful token. When decoded, this token has header the values like:
{
"alg": "ES256",
"typ": "JWT",
"kid": "MYKEYID"
}
and the payload values like:
{
"iat": 1558197586,
"exp": 1573749586,
"iss": "MYTEAMID"
}
I then try to use that in a curl request for a sample artist like `curl -v -H 'Authorization: Bearer <MYTOKEN>' "https://api.music.apple.com/v1/catalog/us/artists/36954"` but it comes back with a 401 error:
