Lesson 5: Error! Unable to locate ContractCode at

[nitindogra]

Getting Error when trying to verify and publish the contract.
Error! Unable to locate ContractCode at " Contract address"

1. Contract is Not Deployed Successfully

npx hardhat verify --network <network-name> <contract-address>

Fix: Deploy the contract again using:

npx hardhat run scripts/deploy.js --network <network-name>

2- Incorrect Network Used for Verification

npx hardhat verify --network goerli <contract-address>

Constructor Arguments Not Provided (Hardhat Verification)

npx hardhat verify --network goerli <contract-address> "arg1" "arg2"

Fix: Get the arguments from the deployment script and pass them:

npx hardhat verify --network goerli <contract-address> "arg1" "arg2"

If the contract uses a .json file for arguments:

npx hardhat verify --network goerli --constructor-args arguments.js <contract-address>
