I have a smart contract that imports from open zeppelin contracts. I have having some trouble verifying the contract through Hardhat. The contract compiles and is deployed on goerli testnet but i get this error when running this command:
Hardhat Command:
npx hardhat verify --network goerli 0x70adB5B0A27da42CE765B44d638b7475aAb8Cf97
Error Message:
An unexpected error occurred:
[Error: ENOENT: no such file or directory, open '/Users/MY_USER_NAME/Desktop/mammoth/artifacts/build-info/1f140c6c1844d1ec9261b1789241547f.json'] { errno: -2, code: 'ENOENT', syscall: 'open', path: '/Users/MY_USER_NAME/Desktop/mammoth/artifacts/build-info/1f140c6c1844d1ec9261b1789241547f.json' }
Here is my smart contract:

pragma solidity ^0.8.17;
import "@openzeppelin/contracts/token/ERC721/ERC721.sol";

console.log("Token Name:", name); // show when tests run
console.log("Token Symbol:", symbol); // show when tests run

}
Here is my Hardhat.config.js file script:
require("@nomicfoundation/hardhat-toolbox");

require("dotenv").config();
