Error message "Truffle 'Migrations' - cb is not a valid function"

I created a straightforward smart contract using Solidity 0.6.6 and now I'm attempting to deploy it on the BSC Testnet.

Here's what my truffle-config.js file looks like (privateKeys is an array with one entry ['0x + privatekey']):

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

However, when I execute "truffle migrate --reset --network bscTestnet" command, I encounter the error message below:

Answer №1

Reported an issue regarding this at: https://github.com/trufflesuite/truffle/issues/4676 Seems like a bug in HardwareWallet2.0.2. Downgrading to HardwareWallet2.0.0 fixed the issue for me.

npm i @truffle/<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="20484457414c4c45540d2929536361622446545b55210e100e10">[email protected]</a>

Answer №2

UPDATE: I managed to resolve the issue by reverting back to version 2.0.1 of @HDWalletProvider and successfully completing the migration process.

It seems like there might be a compatibility issue with the latest version for those who updated today.

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

Encountering the same problem on Polygon Mumbai as well.

The function "cb" is related to the callback function. What's puzzling is that the error message doesn't point to my own code, but rather to 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 makes me suspect that there might be an issue with our 1_initial_migration.js file...even though it's autogenerated so I can't spot any issues...it's quite perplexing.

1_initial_migration.js:

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

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