Cannot deploy to Rinkeby (Lesson7)

[alejandro-mitrovich]

I get an error as such: (I tried with different API KEYs and stuff but nothing worked)

failed to get chainId, falling back on net_version...
An unexpected error occurred:

In hardhat-config.js remove double quotes for url :

    require("@nomiclabs/hardhat-etherscan");
    require("@nomiclabs/hardhat-waffle");
    require("hardhat-gas-reporter");
    require("solidity-coverage");
    require("hardhat-deploy");
    
    const RINKEBY_RPC_URL = process.env.RINKEBY_RPC_URL;
    const PRIVATE_KEY = process.env.PRIVATE_KEY;
    const COINMARKETCAP_API_KEY = process.env.COINMARKETCAP_API_KEY;
    const ETHERSCAN_API_KEY = process.env.ETHERSCAN_API_KEY;
    
    module.exports = {
      // solidity: "0.8.8",
      solidity: {
        compilers: [{ version: "0.8.8" }, { version: "0.6.6" }],
      },
    
      networks: {
        rinkeby: {
-         url: "RINKEBY_RPC_URL",
+         url: RINKEBY_RPC_URL,
          accounts: [PRIVATE_KEY],
          chainId: 4,
          blockConfirmations: 6,
        },
      },
      gasReporter: {
        enabled: true,
        outputFile: "gas-report.txt",
        noColors: true,
        currency: "USD",

        token: "MATIC",
      },
      etherscan: {

That simple?! Yet I could not find the error.
Thank you so much. :)

🙌...😂 happens with everyone, I hope you got the reason why its was showing error because since you wrapped it around double quotes url was litterally this string "RINKEBY_RPC_URL" but we need url to be whats inside our RINKEBY_RPC_URL variable
