404'ing link in No Hardhat config file found error message

[kanej]

Feedback

Running npx hardhat@alpha or pnpx hardhat@alpha, with or without extra arguments (other than --init), in a non-Hardhat directory, shows this error:

    Error HHE3: No Hardhat config file found.
    
    You can initialize a new project by running Hardhat with --init
    
    For more info go to https://hardhat.org/HHE3 or run Hardhat with --show-stack-traces

The URL shown in the message 404s.

• Running npx hardhat or pnpm hardhat in an npm project that has Hardhat installed but doesn’t have a config results in the same error.

We can just drop that last line for now.
