mnemonic.includes in not a function

Question

I've been trying to compile my solidity smart contracts So I'd be able to deploy them on the Ropsten Test network when I run truffle compile I get this error :

TypeError: mnemonic.includes is not a function at normalizePrivateKeys

I don't understand what this typeError means

here's the full message:

using Solidity 0.6.8

Truffle v5.1.26 (core: 5.1.26)

Node v12.16.2

and This is my truffle-config file:

const HDWalletProvider = require("@truffle/hdwallet-provider"); 
const Wallet = require("ethereumjs-wallet.js"); //this line gives

let mainNetPrivateKey = new Buffer(secrets.mainnetPK, "hex");
let mainNetWallet = Wallet.fromPrivateKey(mainNetPrivateKey);
let mainNetProvider = new HDWalletProvider(
  mainNetWallet,
  "https://mainnet.infura.io/v3/***"
);

let ropstenPrivateKey = new Buffer(secrets.ropstenPK, "hex");
let ropstenWallet = Wallet.fromPrivateKey(ropstenPrivateKey);
let ropstenProvider = new HDWalletProvider(
  ropstenWallet,
  "https://ropsten.infura.io/v3/***"
);


module.exports = {  
  networks: {

    development: {
      host: "localhost", // Localhost (default: none)
      port: 7545, // Standard Ethereum port (default: none)
      network_id: "*",
      gas: 4465030, // Any network (default: none)
    },
    ropsten: {
      provider: ropstenProvider,
      network_id: "3",
      gas: 4465030,
    },
    live: {
      provider: mainNetProvider,
      network_id: "1",
      gas: 7500000,
    },
   },

  compilers: {
    solc: {
      version: "0.6.8", 
      },

       }
    },
  },

Any help would be awesome!

There are couple of thing that needs to be fixed

• From the hdwallet-provider documention the first parameter is the mnemonic or the private key. It will fail since you are passing a ethereumjs-wallet instance instead.

• From Truffle documentation a provider should be returned by function. Passing an instance is not correct.

For example in case of ropsten something like this should work:

    ropsten: {
      provider: function () {
        return new HDWalletProvider(
          secrets.ropstenPK,
          "https://ropsten.infura.io/v3/***"
        );
      },
      network_id: "3",
      gas: 4465030,
    },
