Lesson 9: no API token found

[paulcoffee85]

Not sure why but getting "NomicLabsHardhatPluginError" saying no API token found for this network, but it's setup just like the repo.
I tried a few things already to no avail.

Discussion #931 similar but unhelpful.

ERROR:

Verifying contract...
NomicLabsHardhatPluginError: You are trying to verify a contract in 'rinkeby', but no API token was found for this network. Please provide one in your hardhat config. For example:

{

  etherscan: {
    apiKey: {
      rinkeby: 'your API key'
    }
  }
}

@paulcoffee85 You are missing this

etherscan: {
  apiKey: process.env.ETHERSCAN_API_KEY,
},

make sure to rename the env variable according to your variable name.

Thanks @alymurtazamemon , I had tried it earlier but not directly under module.exports, was in defaultNetwork. Thanks again.
