Can't deploy smart contract using Ledger Nano S as provider for Truffle

[FilipLaurentiu]

I can't deploy smart contract using Ledger Nano S as provider for Truffle
Here is my code for deploying on ropsten

const LedgerWalletProvider = require('@ledgerhq/web3-subprovider');
const createLedgerSubprovider = LedgerWalletProvider.default;
const TransportNodeHid = require('@ledgerhq/hw-transport-node-hid-singleton').default;
const ProviderEngine = require('web3-provider-engine');
const RpcSubprovider = require('web3-provider-engine/subproviders/rpc');
// const logger = require("@ledgerhq/logs");

const localNode = 'http://127.0.0.1:8545';

// logger.listen(log => console.log(log));
const getTransport = () => TransportNodeHid.create();
const ledger = createLedgerSubprovider(getTransport, {
    networkId: 3, paths: ["44'/1'/x'/0/0", "44'/1'/0'/x"], askConfirm: false,
});

const engine = new ProviderEngine();
engine.addProvider(ledger);
engine.addProvider(new RpcSubprovider({ rpcUrl: localNode }));
engine.start();

module.exports = engine;

and Truffle config

require("dotenv").config();
const gasPrice = require("./get_gas_price");
const Web3 = require("web3");
const web3 = new Web3();

const LedgerProviderRopsten = require('./ledger-provider-ropsten');
const LedgerProviderMainnet = require('./ledger-provider-mainnet');

module.exports = {
  networks: {
    mainnet: {
      provider: () => LedgerProviderMainnet,
      network_id: 1,
      gasPrice: web3.utils.toWei((gasPrice.fast / 10).toString(), "gwei"),
    },
    ropsten: {
      provider: () => LedgerProviderRopsten,
      network_id: 3,
      gasPrice: web3.utils.toWei("3", "gwei"),
    }
  },
  compilers: {
    solc: {
      version: "0.6.8",
      settings: {
        optimizer: {
          enabled: true
        }
      }
    }
  }
};

The error is

Web3ProviderEngine does not support synchronous requests..

Truffle v5.1.29 (core: 5.1.29)
Node v10.21.0
@ledgerhq/hw-transport-node-hid-singleton 5.16.0
@ledgerhq/logs 5.15.0
@ledgerhq/web3-subprovider 5.16.0

Mention that using other provider in truffle it work without problem.

    testnet: {
      provider: () => new HDWalletProvider(process.env.MNEMONIC, process.env.BLOCKCHAIN_NODE_ROPSTEN),
      network_id: "*"
    },

I just remove the gasPrice field from configuration and error disappear but I have another problem, after deploying first contract it remains stuck and keep counting confirmation block.

filip@filip-pc: yarn deploy
yarn run v1.22.4
$ truffle deploy -f 2 --to 2 --network ropsten --skip-dry-run --verbose-rpc --reset --describe-json

I'm also getting the encountering the same error with migrations being stuck, did you find a way to solve this?

[FilipLaurentiu]

No fix for this. It seems that problem is with truffle trufflesuite/truffle#3091 (comment)

Hi @FilipLaurentiu

Did you find a way to use the new ledger with truffle migration?
