Is there a way to remove 'iat' option from jwt payload in jsonwebtoken library typescript?

Question

I want to remove 'iat' option from header for the creation of correct request to the external server. I've tried to do something like this

let token = jwt.sign(
    {payload: payload, iat: undefined},
    generateAndGetDeviceKey(),
    { algorithm: 'HS512' }
);

but it doesn't work. I got error

Uncaught (in promise) Error: "iat" should be a number of seconds

Answer 1

You can pass the noTimestamp option, which will prevent adding iat.

Something like this should work.

let token = jwt.sign(
    {payload: payload},
    generateAndGetDeviceKey(),
    { algorithm: 'HS512', noTimestamp: true }
);
