@tonyaneke I have updated it

const deploymentReceipt = await contract.deploymentTransaction().wait(2)

And also address is changed to target now.

console.log(`Contract deployed to ${contract.target}`)

[tonyaneke]

This returns that another error

[SynhardSone]

try this const transactionReceipt = await contract.deploymentTransaction().wait(1);

[Deejaylazer]

still not working pls help me out

[Shadow-Walker96]

This error ethers.JsonRpcProvider is because the current ethers library when installed is currently ^6.0.
so try uninstalling ether by typing this code in your command line -> yarn remove ethers
after that yarn add ethers@5.6.2

[Deejaylazer]

still having the same issue

Removing and downgrading resolved my issue with this problem, thank you man

[Hruthik5124]

This works for me.

const contractFactory = new ethers.ContractFactory(abi,binary,wallet);
console.log("Deploying please wait....");
const contract = await contractFactory.deploy();
const deploymentReciept = await contract.deploymentTransaction()?.wait(1);
