To Reproduce Steps to reproduce the behavior:

npx hardhat --network sepolia run scripts/deploy.js --show-stack-traces
Error HH100: Network sepolia doesn't exist
HardhatError: HH100: Network sepolia doesn't exist

• OS [ MacOs Monterey (12.7)]

defaultNetwork: "sepolia",

networks: {
  sepolia: {
    url: RPC_API_KEY,
    // accounts: [WALLET_PRIVATE_KEY],
    accounts: [`0x${WALLET_PRIVATE_KEY}`],
    chainID: 5,
  },
},

Following steps helped me to unblock the issue:

1. Adding defaultNetwork and defining sepolia under networks of hardhat.config.js.
2. Executing without --network option. (npx hardhat run scripts/deploy.js)

I think this change has to be mentioned in the lesson, when users hit failure.

Hey @sandeepV2
Sorry for the very, very long wait.
Please be sure to enter your command like so:
npx hardhat run scripts/deploy.js --network sepolia
Your terminal needs to read the commands in the correct order. Here hardhat will recognise the following run as a command. If followed by --network, it will throw an error because Hardhat won't recognise it as a command.
Hope this helps 😃
