I tried to send a request to my contract using ethersjs like this:

const web3Modal = new Web3Modal()

const connection = await web3Modal.connect()

const provider = new ethers.providers.Web3Provider(connection)

const signer = provider.getSigner()

const contract = new ethers.Contract(Contract, Market.abi, signer)

const price = ethers.utils.parseUnits(price.toString(), 18)



//const price = web3.utils.toWei(nft.price);

//const price = ethers.BigNumber.from(nft.price.toString()).toHexString();

   

const transaction = await contract.createSale(address, price)



await transaction.wait()

This code shows an error, I have tried all the solutions in this world, but nothing worked. => versions: nodejs 14.15, npm 8, web3 1.6, ethers 5.5

Any help?
