Creating fhevm js instance with chainid causes error

[Abhay-2811]

With chain id

Code:

const { createInstance } = require("fhevmjs");

const createFhevmInstance = async () => {
  return createInstance({
    chainId: 9000,
    networkUrl: "https://rpc.encifher.io",
    gatewayUrl: "https://gateway.rpc.encifher.io",
  });
};
createFhevmInstance().then((instance) => {
  console.log(instance);
});

Error:

/Users/abhay/rize/encifher/signet-test-node/node_modules/fhevmjs/lib/node.cjs:179
        throw new Error('Impossible to fetch public key from network (wrong url?)');
              ^

Without Chain id

Code:

const { createInstance } = require("fhevmjs");

const createFhevmInstance = async () => {
  return createInstance({
    networkUrl: "https://rpc.encifher.io",
    gatewayUrl: "https://gateway.rpc.encifher.io",
  });
};
createFhevmInstance().then((instance) => {
  console.log(instance);
});

Output:

  generateKeypair: [Function: generateKeypair],
  createEIP712: [Function (anonymous)],
  reencrypt: [AsyncFunction (anonymous)],
  getPublicKey: [Function: getPublicKey]
}
