Truffle '"Migrations" -- cb is not a function'

Question

I wrote a simple smart contract in Solidity 0.6.6 that I'm trying to deploy to the BSC Testnet.

This is what I have in my truffle-config.js file (privateKeys is an array with a single entry of ['0x + privatekey']:

networks: {
   bscTestnet: {
      provider: () => new HDWalletProvider(
        privateKeys,
        'https://data-seed-prebsc-1-s1.binance.org:8545/'
      ),
      network_id: 97,
      skipDryRun: true
   }
}

When I run the command "truffle migrate --reset --network bscTestnet" I get the following error:

Compiling your contracts...
===========================
> Everything is up to date, there is nothing to compile.



Starting migrations...
======================
> Network name:    'bscTestnet'

Answer 1

Opened an Issue a about it: https://github.com/trufflesuite/truffle/issues/4676 I guess its a bug in HardwareWallet2.0.2. Reverting to HardwareWallet2.0.0 solved the problem for me

 npm i @truffle/hdwallet-provider@2.0.0

Answer 2

I am currently having the exact same error with ethereum testnet (ropsten). Truffle v5.4.29 Node v16.13.2

Answer 3

I'm having the exact same issue

Truffle v5.4.31 Node v14.16.0

Answer 4

UPDATE: Right, workaround: I rolled @HDWalletProvider back to v2.0.1 and was able to migrate.

I assume there must be an issue with the new version for ppl who updated today.

================

Same problem with Polygon Mumbai.

Function "cb" refers to the callback function. The strange part is the error message doesn't reference my own code at all; it references the migrations.js located in:

<.nvm/versions/node/v16.11.1/lib/node_modules/truffle/build/webpack:/packages/deployer/src/deployment.js:365:1 at processTicksAndRejections (node:internal/process/task_queues:96:5>

This leads me to believe there's a problem with out 1_initial_migration.js... however that's auto-generated so I can't see any problem... it's strange.

1_initial_migration.js:

const Migrations = artifacts.require("Migrations");

module.exports = function(deployer) {
  deployer.deploy(Migrations);
};
