Confusing estimateGas error message in Hardhat node

[fvictorio]

A user got this output in their node:

I don't have reproduction steps, although it can probably be simulated locally by hardcoding some throw somewhere. The point is that a message like that is very confusing and we should either not show anything at all or show something better.

My guess of how to reproduce this:

1. Check the part of the code that throws when an unrecognized error happens
2. Hardcode that to make it always throw
3. Start an hh node and send an eth_estimateGas

EDIT: I'm pretty sure that most of the time this happens because of #3474; check that issue for an explanation and a workaround. This issue is still valid though: we should show a better error message when an unhandled error is thrown.

EDIT 2: we should improve this for all JSON-RPC methods, not just eth_estimateGas. See for example #1311.

have this issue too with apple m1 and node v18.4.0, hardhat 2.10.2

I have the same issue. Hardhat 2.11.0
I'm trying to test smartcontract locally.

My steps to reproduce:

1. Fork the mainnet:

A part of hardhat.config.ts

networks: {
    hardhat: {
      allowUnlimitedContractSize: true,
      forking: {
        url: "https://eth-mainnet.g.alchemy.com/v2/<ALCHEMY_KEY>",
      }
    },
    localhost: {
      allowUnlimitedContractSize: true,
      chainId: 31337,
      accounts: [`PRIVATE_KEY1`, `PRIVATE_KEY2`],
    },
}

2. Auth in metamask, connect to network localhost:8545 with chainId 31337
3. Add hardhat account in metamask with PRIVATE_KEY1
4. Deploy smartcontract
5. Trying to send eth to smartcontract in metamask. Button, which starts the transaction, is inactive

Here, what I have in console:

I confirm. I'm facing the same issue.
Absolutely reproducible.

It looks like the issue is in MetaMask browser extension.

It works just fine with MetaMask for Android.
All the transactions to hardhat node goes well when performed from mobile wallet but not from a browser extension.

I tried Chrome and FireFox extensions.

Finally I got it!
It took almost whole day to figure out what is the cause.

The default chainId of Hardhat node is 31337 and this causes the issue.
I changed it to 1337 and everything works now.

/// hardhat.config.js:

/** @type import('hardhat/config').HardhatUserConfig */
module.exports = {
  solidity: "0.8.17",
  networks: {
    hardhat: {
      chainId: 1337, // default is 31337
    }
  }
};

I'm sure the root of the problem is out there.
I hope somebody will figure it out and get it fixed eventually.

As described here:
#3089 (comment)
I'm getting this error as well.
But changing the chainId didn't fix the issue.

May it be related to this?
