ProviderError: submit transaction to pool failed: Pool(InvalidTransaction(InvalidTransaction::Payment))

Question

Hi I am trying to use Hardhat to deploy Ethereum smart contracts to my parachain with Frontier EVM inside. The Hardhat uses my own Typescript file to deploy contracts like this one: https://hardhat.org/hardhat-runner/docs/guides/deploying

Then I got this error: ProviderError: submit transaction to pool failed: Pool(InvalidTransaction(InvalidTransaction::Payment))

I am not sure what happened... My Hardhat can run Ethereum smart contract tests and deploy contracts to a local Ethereum network with no problem. The contract can be deployed to my parachain via Remix and MetaMask, too. but somehow Hardhat cannot directly deploy smart contracts...

I solved it... Do not duplicate Hardhat plugin imports.

import { task, HardhatUserConfig } from "hardhat/config";
import { ethers } from "ethers";
import '@nomiclabs/hardhat-waffle'
import "@nomiclabs/hardhat-ethers";
import { config as dotenvConfig } from "dotenv";//to avoid conflict with const config: HardhatUserConfig = {}

Also wait for previous transaction to go through first:

const tx = await owner.sendTransaction({ 
    to: ERC1820_DEPLOYER, value: toWei(0.08) 
});
const receipt = await tx.wait().catch((err: any) => {
    console.log("Error 001:", err);
    return false;
});
