iat and exp properties of decoded object are undefined

[dev123dev123]

var token = jwt.sign('hello', secret, expiration);
var decoded = jwt.decode(token);

console.log(decoded.iat); // undefined
console.log(decoded.exp); // undefined

Not sure if iat and exp should display anything but undefined when a string payload is sent instead of an object.

The signed token in this case will not have exp/iat because it is an string. Try signing a JSON instead

@jfromaniello

var token=jwt.sign(member,app.get('superSecret'),{
expiresInMinutes:40
});

I am using this code to generate a token. members is the data from the database. and the token does not have iat and exp. what is wrong?

[jfromaniello]

@abhinav76 please send me an example token

I added a note.
