'Error in Deployment in Binance Testnet : Could not create addresses from your mnemonic or private key(s)

I was trying to deploy my contract to Binance Smart Chain Testnet and I got this error. I am using truffle and also successfully installed truffle HD wallet Provider.

Truffle Error:-

Error: Could not create addresses from your mnemonic or private key(s). Please check that your inputs are correct.

I had the same problem, in my case I simply forgot to add

require("dotenv").config();

Solution 2:[2]

I faced a similar problem, and found the solution to use private key instead of mnemonic:

in your .env :

API_URL = "https://ropsten.infura.io/v3/your project id" # note: put your node url here
PRIVATE_KEY = "your account private key"

and in your truffle-config.js:

module.exports= {
....
rospten: {
  provider: () => new HDWalletProvider(
    process.env.PRIVATE_KEY,
    process.env.API_URL), 
    network_id: 3,
    gas: 1000000,
    gasPrice: 20000000000,
    confirmations: 2,
    timeoutBlocks: 200000,
 }
....
}

Might be the way you're defining your private key.

Instead of a mnemonic, you can alternatively provide a private key or array of private keys as the first parameter. When providing an array, address_index and num_addresses are fully supported.

var HDWalletProvider = require("truffle-hdwallet-provider");
//load single private key as string
var provider = new HDWalletProvider("3f841bf589fdf83a521e55d51afddc34fa65351161eead24f064855fc29c9580", "http://localhost:8545");

// Or, pass an array of private keys, and optionally use a certain subset of addresses
var privateKeys = [
  "3f841bf589fdf83a521e55d51afddc34fa65351161eead24f064855fc29c9580",
  "9549f39decea7b7504e15572b2c6a72766df0281cea22bd1a3bc87166b1ca290",
];
var provider = new HDWalletProvider(privateKeys, "http://localhost:8545", 0, 2); //start at address_index 0 and load both addresses
