I tried deploying to the rinkeby network with Yarn hardhat run scripts/deploy.js --network rinkeby, i got this error below

• Invalid value undefined for HardhatConfig.networks.rinkeby.url - Expected a value of type string.
• Invalid account: #0 for network: rinkeby - Expected string, received undefined

To learn more about Hardhat's configuration, please go to https://hardhat.org/config/

My hardhat.config.js

require("@nomiclabs/hardhat-waffle");
require("dotenv").config()

task("accounts", "Prints the list of accounts", async (taskArgs, hre) => {
const accounts = await hre.ethers.getSigners();

for (const account of accounts) {
console.log(account.address);
}
});

const RINKEBY_RPC_URL=process.env.RINKEBY_RPC_URL
const PRIVATE_KEY=process.env.PRIVATE_KEY

module.exports = {
defaultNetwork:"hardhat",
networks:{

rinkeby:{
    url:RINKEBY_RPC_URL,
    accounts:[PRIVATE_KEY],
    chainId:4,

},

},
solidity: "0.8.8",

};

What line does the error log point to (where the error originates from)?
Can you console.log process.env.RINKEBY_RPC_URL and process.env.PRIVATE_KEY to make sure you have the correct values?

[baocongchen]

Looks like process.env.RINKEBY_RPC_URL and process.env.PRIVATE_KEY values are undefined.

Make sure in your .env the format is Object ie: RINKEBY_RPC_URL=https://eth-rinkeby.alchemyapi.io/v2/
PRIVATE_KEY=
