        _mint(recipient, newItemId);
        _setTokenURI(newItemId, tokenURI);

        return newItemId;
    }

    console.log("Contract deployed to address:", myNFT.address)
  }
  
  main()
    .then(() => process.exit(0))
    .catch((error) => {
      console.error(error)
      process.exit(1)
    })

That error is clear. you do not have sufficient funds. This is how you are getting the account information:

const { API_URL, PRIVATE_KEY } = process.env;

I had an issue with webpack once destructuring process.env. Try this

// ASSUMING you pass correct private key here
const PRIVATE_KEY  = process.env.PRIVATE_KEY;

console.log the private key.

If it does not get resolved, that means you are not passing the correct PRIVATE_KEY.
