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);
