Error deploying Ethernaut on Local Network

Security Ethernaut

Hello! I am trying to use ethernaut to get some ctf practice on local since it is much easier to manage there but I am having trouble going through the steps to successfully deploy it on a local network.

This is what my terminal returns after following step 6 of the https://github.com/OpenZeppelin/ethernaut guide:
