Verify Error "ProviderError: Address xxxx is not whitelisted" - Lesson 6 🧨🤯

[midnightprofessional]

While following Lesson 6, I am encountering this error in verifying the SimpleStorage contract in Etherscan with @nomiclabs/hardhat-etherscan on Goerli.

The codes successfully deployed the contract and call it on Goerli, so the Goerli credential is valid.

I spent a few hours Googling but found little relevant answers. 🤯

% npx hardhat run scripts/deploy.js --network goerli

As the above terminal log shows, the exception was trigged whilte calling run("verify:verify",....)

async function verify(contractAddress, args) {
    console.log(`Verify contract...`);
    try {
        await run("verify:verify", {
            address: contractAddress,
            constructorArguments: args,
        });
    } catch (e) {
        if (e.message.toLowerCase().includes("already verified")) {
            console.log("Already Verified!");
        } else {
            console.log(e);
        }
    }
}

Thanks a lot for the help.

@midnightprofessional push the code to GitHub and leave a link here, need to see your settings for it.

Thanks for looking into it @alymurtazamemon , GitHub link is in the original post. Here it is again.

Before I look at the repo, please make sure your .env is correct

[midnightprofessional]

Thanks @krakxn .

I can confirm my .env file is present and correct locally.
Please see Terminal logs, the contract is able to deploy and call with Goerli, so the Private Key and RPC Url must be correct.

I have console log out ETHERSCAN_API_KEY before consuming it too, so it's should not be an .env issue.

GOERLI_RPC_URL=https://eth-goerli.g.alchemy.com/v2/xxx
PRIVATE_KEY=xxx
ETHERSCAN_API_KEY=xxx

That is fine
