Inherited methods return "missing revert data" instead of revert string

missing revert data

Describe the Problem

When calling an inherited function which reverts, ethers throws “missing revert data in call” error instead of returning the supplied revert string. (This appears to work as expected in remix).

In the example below, I would expect the method call to return `forced revert’ but instread returns

Error: missing revert data in call exception [ See: https://links.ethers.org/v5-errors-CALL_EXCEPTION ] (error={"stackTrace":[{"type":4,"sourceReference":{"function":"getAttribute","contract":"Mymain","sourceName":"contracts/reader.sol","sourceContent":"// SPDX-License-Identifier: GPL-3.0\n\npragma solidity 0.8.6;\n\ncontract reader {\n\n    address myAddress;\n    \n\n    function getAttribute() public pure returns(string memory) {\n        \n        require(false, \"forced revert\");\n        return \"foo\";\n    }\n}","line":12,"range":[191,222]},"message":{"value":{"type":"Buffer","data":[8,195,121,160,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,32,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,13,102,111,114,99,101,100,32,114,101,118,101,114,116,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0]},"_selector":"08c379a0"},"isInvalidOpcodeError":false}]}, data="0x", code=CALL_EXCEPTION, version=providers/5.6.2)

This test code that produces this error is (hardhat typescript) is

import { ethers } from "hardhat";
import {Mymain} from '../typechain';

describe.only('Mymain',  () => {
    let mymain : Mymain;
    before(async () => {
        let bf = await ethers.getContractFactory("Mymain");   
        mymain = await bf.deploy();
    });

    it('test mymain', async () => {
        let val = await mymain.getAttribute();
       
    });
});

Code Snippet

    function getAttribute() public pure returns(string memory) {      
        require(false, "forced revert");
        return "foo";
    }
}

contract Mymain is reader {

It’s not yet released on hardhat (please see https://github.com/ethers-io/ethers.js/discussions/2849#discussioncomment-2640553).
