NomicLabsHardhatPluginError: Invalid API Key

[vamankumar00]

Hi!
I am getting this error: "NomicLabsHardhatPluginError: Invalid API Key", while running contract verification.
I am using goerli test net and using apikey from etherscan.io.
Any help will be appreciated thanks.

What's your .env and hardhat.config.js look like ?

module.exports = {
  networks: {
    mainnet: { ... }
  },
  etherscan: {
    // Your API key for Etherscan
    // Obtain one at https://etherscan.io/
    apiKey: "YOUR_ETHERSCAN_API_KEY"
  }
};
