The error call revert exception means that:

Method reverts during its execution. Method is not present in your contract. Contract not deployed on the network you're connected to (or address put is incorrect). Your network has some temporary outages.

Why gas and gasPrice in hardhat.config?

const network = await ethers.getDefaultProvider().getNetwork(); i get homestead all the time. i use const network = await hre.network.name;

what is this code referring to? i often get timeout error 40000ms when using enter function await this.lottery.enter(overrides = {value: ethers.utils.parseUnits("2", 17)});

const LinkToken = new ethers.Contract(link_token, abi, signer); await LinkToken.transfer(this.lottery.address, 1000000000000000);
