Deployment issue using hardhat-ledger, error message vague

[yohanelly95]

Version of Hardhat

2.20.1

What happened?

Running a deploy script, that deploys a set of contracts on chain using a ledger hardware wallet using the package "@nomicfoundation/hardhat-ledger": "^1.0.2". Note: The issue seems to specific to the RPC/network. Need to know what the exact issue so I can try resolving it. The same script works on Polygon for eg.

npx hardhat run scripts/deployBridge.js --network skaleChain

The error received:

Deploying ResultManager contract...
✔ [hardhat-ledger] Connecting wallet
✔ [hardhat-ledger] Waiting for confirmation
ProviderError: Invalid RPC parameters.
    at HttpProvider.request (bridge-proxy/node_modules/hardhat/src/internal/core/providers/http.ts:88:21)
    at processTicksAndRejections (node:internal/process/task_queues:95:5)
    at LedgerProvider.request (bridge-proxy/node_modules/@nomicfoundation/hardhat-ledger/src/provider.ts:137:18)
    at EthersProviderWrapper.send (bridge-proxy/node_modules/@nomiclabs/hardhat-ethers/src/internal/ethers-provider-wrapper.ts:13:20)

Minimal reproduction steps

The deployBridge script:

const hre = require("hardhat");
require('dotenv').config();

const SIGNER_ADDRESS = process.env.SIGNER_ADDRESS ||
const { checkTimeDifference } = require('./validateTimestamp');

async function main() {
  console.log("Validating block timestamp of the deploying chain")

  await checkTimeDifference()
  .then(() => console.log('Finished checking time difference.'))
  .catch(error => console.error('An error occurred:', error));


  console.log("Deploying ResultManager contract...");
  const signer = await hre.ethers.getSigner();

  const ResultManager = await hre.ethers.getContractFactory("ResultManager");
  const resultManager = await ResultManager.deploy(SIGNER_ADDRESS);
  console.log("ResultManager contract deployed at:", resultManager.address);
}

// We recommend this pattern to be able to use async/await everywhere
// and properly handle errors.
main().catch((error) => {
  console.error(error);
  process.exitCode = 1;
});

Hardhat config of the network used:

skaleChain: {
      chainId: 1564830818,
      url: "https://mainnet.skalenodes.com/v1/honorable-steel-rasalhague",
      ledgerAccounts: [
        "", // specify Ledger Address here (required) 
      ],
      timeout: 600000, 
    }

Are you able to run this script (or a similar script) without using ledger? Basically can we isolate whether the RPC error is due to hardhat-ledger or the general interaction of Hardhat and the skaleChain.

you're right, I could run the script using accounts["PRIVATE_KEY"](not using ledgerAccounts). Error seems to be specific to hardhat-ledger. I need to deploy using these contracts using the hardware wallet though @kanej any suggestions on how to go about this. I cannot export the hardware wallets private key

We will have to investigate what is happening in hardhat-ledger - intuitively a transaction that works without going through ledger should work when it does so. Is there any information in skaleChain community that suggests with Ledger based transactions?

I will check with the Skale chain community and get back. In the mean time;
