JWT sign makes same result if it is called in a raw

[lcs86-dev]

const { readFileSync, writeFileSync } = require("fs");

const jsonKeystore = JSON.stringify(
	{
		"keys":[
			 {
					"crv":"Ed25519",
					"x":"x",
					"d":"d",
					"kty":"OKP",
					"kid":"session"
			 }
		]
 }
)

let keyStore;
try {
  keyStore = JWKS.asKeyStore(JSON.parse(jsonKeystore));
} catch (err) {
  if (err.code == "ENOENT") {
    keyStore = new JWKS.KeyStore();
    keyStore.generateSync("OKP", "Ed25519", { kid: "session" });
    writeFileSync(keyStorage, JSON.stringify(keyStore.toJWKS(true)));
  } else {
    console.log(err)
  }
}

const createJwt = (claim) => {
  const mpcKey = keyStore.get({ kid: "session" });
  return JWT.sign(claim, mpcKey, { expiresIn: '1 min' }); 
};

const claim = {
	uid: 1,
	op: "gen",
	data: { dsa: "ecdsa", curve: "secp256k1" },
};
const interval = 100

console.log(createJwt(claim))
setTimeout(() => {
	console.log(createJwt(claim))
}, 100)

If the interval time is short like 100 ms, createJwt makes the same result.
I want to make different tokens whenever i call JWT sign.
What can i do to make this work?

Introduce a random value in your token payloads or stop using a deterministic JWS algorithm.

Thanks for replying. Adding a random value works like a charm.
