Provider error hardhat

Question

When i want to deploy my contract with this command:

npx hardhat run --network goerli scripts/deploy.js

I get this error:

ProviderError: HttpProviderError at HttpProvider.request (/Users/alirezamac/Documents/Token-dex/node_modules/hardhat/src/internal/core/providers/http.ts:78:19)

And here is my config file:

require("@nomicfoundation/hardhat-toolbox");
require ("dotenv").config()

module.exports = {
  solidity: "0.8.17",
  networks: {
    goerli: {
      url: process.env.INFURA_GOERLI_ENDPOINT,
      accounts: [process.env.PRIVATE_KEY],
      chainId: 5
    },
  },
};

and also this is my deploy file:

const hre = require("hardhat");

async function main() {
 const Token = await hre.ethers.getContractFactory("MyToken")
 const token = await Token.deploy();
 await token.deployed()
console.log("Congratulations!! Your token deployed, Here's token address:", token.address);

 const Dex = await hre.ethers.getContractFactory("Dex2")
 const myDex = await Dex.deploy(token.address)
 await token.deployed()

 console.log("Here's your dex contract address:", myDex.address);

}
main().catch((error) => {
  console.error(error);
  process.exitCode = 1;
});

Answer 1

You can add some lines to node_modules/hardhat/internal/core/providers/http.js to debug. After every isErrorResponse check add: console.log(response) or console.log(jsonRpcResponse).

Most likely it's an error inside your contracts or deploy script (or both).

Answer 2

Thre is a typo in await token.deployed() should be myDex.deployed()

That could be the reason the provider is reverting without any reason

Answer 3

Solved this error by looking the ganache's console and seeing that the tx was reverted due to an error caused by incorrect assignment of an account to a role.
