Facing error on deploying contract in Binance Smart Chain

Question

I am trying to deploy a test contract on Binance Smart Chain network. I am using metamask, and truffle to create and test the contract. My folder structure looks like this

const HDWalletProvider = require('truffle-hdwallet-provider-privkey');
    const privateKeys = process.env.PRIVATE_KEYS || ""
    
    module.exports = {
      networks: {
        development: {
          host: "127.0.0.1",
          port: 7545,
          network_id: "*"
        },
        binancetestnet: {
          provider: function() {
            return new HDWalletProvider(
              privateKeys.split(','), // Array of account private keys
              `https://data-seed-prebsc-1-s1.binance.org:8545/${process.env.INFURA_API_KEY}`// Url to an Ethereum Node
            )
          },
          gas: 5000000,
          gasPrice: 25000000000,
          network_id: 97
        }
      },
    
      // Set default mocha options here, use special reporters etc.
      mocha: {
        // timeout: 100000
      },
    
      // Configure your compilers
      compilers: {
        solc: {
           version: "0.7.3",    // Fetch exact version from solc-bin (default: truffle's version)
          // docker: true,        // Use "0.5.1" you've installed locally with docker (default: false)
          // settings: {          // See the solidity docs for advice about optimization and evmVersion
          //  optimizer: {
          //    enabled: false,
          //    runs: 200
          //  },
          //  evmVersion: "byzantium"
          // }
        }
      }
    };

I have attached all the code with errors I am facing. Can anyone help me with it? I have also Installed the HD Wallet provider as well. Truffle compile worked successfully.

you are missing source code module called truffle-hdwallet-provider-privkey , verify you have the files in the correct directory — Nulik
i have installed using npm install @truffle/hdwallet-provider It installed Successfully. But I encountered a new problem while deploying — Bsc Talk
