jsonwebtoken.sign() fails with expiresIn option set

Question

I need to get a token by signing a user ID with JWT:

var token = jwt.sign(accounts[request.headers.login].id, privateKey, {expiresIn: 60});

Where id and privateKey are strings.

The error is Error: Uncaught error: "expiresIn" should be a number of seconds or string representing a timespan eg: "1d", "20h", 60. If I remove options object at all, it works, but without options I need to set.

The issue seems to be simple but I don't know how to fix it, what am I doing wrong?

Answer 1

https://www.npmjs.com/package/jsonwebtoken#jwtsignpayload-secretorprivatekey-options-callback

payload could be an object literal, buffer or string. Please note that exp is only set if the payload is an object literal.

Answer 2

Set the payload as an object if you want to be able to set the expiresIn option

var token = jwt.sign(
    {id: accounts[request.headers.login].id}, // object and not string
    privateKey,
    {expiresIn: '60d'} // added days, default for ex 60 would be ms, you can also provide '1h' etc
