Getting error: 400 post transactions: raw: rlp: expected input list for []*tx.Clause, de... on eth_sendRawTransaction

[muhammadusmanuet]

import * as thor from "@vechain/web3-providers-connex";
import { ethers } from "ethers";
import { BrowserProvider, Wallet } from "ethers";
import { Driver, SimpleNet, SimpleWallet } from "@vechain/connex-driver";
import { Framework } from "@vechain/connex-framework";

const wa = new SimpleWallet();
wa.import(wallet.privateKey);
const net = new SimpleNet(conf.rpcURL);
const driver = await Driver.connect(net);
const connexObj = new Framework(driver);
const provider = thor.ethers.modifyProvider(
  new ethers.BrowserProvider(
    new thor.Provider({
      connex: connexObj,
      wallet: wa,
      net: net,
    }),
  ),
);

const contract = Bridge__factory.connect("0x7111eb5f8d9dA472e9608f2ab3De275C040D60B2", new Wallet(wallet.privateKey).connect(provider));
contract.addValidator("0x...", [{
  signerAddress: '0x...',
  signature: '0x...'
}])

while calling the above function on contract getting error:
