Had the same issue. This worked for me: const privateKey = await readFile(filePath, { encoding: 'utf-8' }) const now = Math.floor(Date.now() / 1000) return jwt.sign( { iss: issuer, iat: now, exp: now + 15776999, // ~ less than 6 months from now origin: ['http://localhost:3000'], // recommended in the docs }, privateKey, { header: { alg: 'ES256', kid, typ: 'JWT', }, }, )

Hi @scottfinkelstein what version of the API are you using? I've got the same issue but using V3. No errors or anything

@hntdhs you can create an auth token with something similar to this: const generateAppleMusicToken = async ({ filePath, issuer, kid, }: { filePath: string; issuer: string; kid: string }) => { console.log('Generating apply music token...') const privateKey = await readFile(filePath, { encoding: 'utf-8' }) return jwt.sign({}, privateKey, { issuer, expiresIn: '180d', header: { alg: 'ES256', kid, }, }) } you should have a .p8 file if you've signed up as an apple developer and created a key.
