[obc92]

I got this error forking the network:

Error HH8: There's one or more errors in your config file:

  * Invalid value {"chainId":31337,"forking":{}} for HardhatConfig.networks.hardhat - Expected a value of type HardhatNetworkConfig.

For more info go to https://hardhat.org/HH8 or run Hardhat with --show-stack-traces
error Command failed with exit code 1.

This also my code, added all requisits to fork but still not working.

module.exports = {
  // solidity: "0.8.8",
  solidity: {
      compilers: [{version: "0.8.8"}, {version: "0.6.6"}, {version: "0.4.19"}],
  },

      },

      },
  },

    deployer: {
      default: 0,
    },
  },
  etherscan: {

}

I came up with the same issue :(, what's your solution?

[obc92]

I really don't remember, try to delete node_modules and run yarn to reinstall. Can you paste your config file also maybe I can help.
If I didn't post the answer it usually means that is some stupid error.
