I had the same problem.
The problem was solved by resetting the saved data by executing the following command described in the GitHub repository> README.
npx hardhat node npx hardhat run scripts/deploy.js --network localhost npm run dev
Probably the error is due to some problem with the saved data.
but i want to deploy this to ropsten not localhost so other can interact with it
