Does the repository support ethers ^6.6.0

[xuht724]

I am using

const { Multicall } = require("ethereum-multicall");
const poolABI = require('./utils/uniswapPairV2ABI.json');
const { ethers } = require("ethers");
const { wsURL } = require("./config.js");
const { Web3 } = require("web3");

const rpcURL = "My RPC URL";
// const web3 = new Web3(rpcURL);
const calls = [
    { methodName: 'token0', methodParameters: [] },
    { methodName: 'token1', methodParameters: [] },
    { methodName: 'factory', methodParameters: [] }
];

// A pair address
const contractAddress = "0xB6909B960DbbE7392D405429eB2b3649752b4838";

const callObject = {
    reference: "result0",
    contractAddress: contractAddress,
    abi: poolABI,
    calls: calls
};

const provider = new ethers.JsonRpcProvider(rpcURL);
console.log(provider);

const myMulticall = new Multicall({
    ethersProvider: provider,
    tryAggregate: true,
});
async function getResult() {
    let resp = await myMulticall.call(callObject);
    console.log(resp.results.result0.callsReturnContext);

}
getResult();

It throws out the error Error: invalid signer or provider (argument="signerOrProvider", value={}, code=INVALID_ARGUMENT, version=contracts/5.7.0)

The ethers version is 6.6.1. I want to ask if the error is caused by the version conflict.
