Lesson 9- AssertionError: Expected transaction to be reverted with reason 'Raffle__SendMoreToEnterRaffle', but it reverted with a custom error

[VasuShrivastava]

I got tons of error in the process, maybe my dependencies were not right. I shifted to ethers v5 and was getting TypeError: (0 , ethers_1.getAddress) is not a function this error. After searching on google and these discussions for solution I upgraded to ethers6.6.2 and started getting this error AssertionError: Expected transaction to be reverted with reason 'Raffle__SendMoreToEnterRaffle', but it reverted with a custom error.

Here is the Link to the repo https://github.com/VasuShrivastava/hardhat-raffle-fcc.git

Here is the error-

As I can see from your contract, from there you are reverting with error Raffle__NotEnoughEth.
So, put this error in your test, and it will work fine.

[VasuShrivastava]

Hey, thanks for the response. Yes I noticed this the moment after I put up the question and made changes according to that, but it was giving the same error.

My bad I forgot to update the repo, but now its been updated https://github.com/VasuShrivastava/hardhat-raffle-fcc/tree/main, please take a look and help me resolve this.

Refer to this to handle custom errors.

Nah man, it still doesn't work. I tried both with and without custom error and all around it, but it was giving this same error. this is what I have used. Can you test it on your local environment and check, cause even after all the alterations its still not working.

describe("enterRaffle", async function(){
        it("reverts when you don't pay enough", async () => {
            await expect(raffle.enterRaffle({value: 0})).to.be.revertedWithCustomError(raffle, "Raffle__NotEnoughEth").withArgs(0);
        });
    });

Here is the error. take a look.

[shikhar229169]

Yes, it is giving me same error.
I recommend you to refactor your hardhat config file:

require("@nomiclabs/hardhat-waffle");
require("@nomiclabs/hardhat-etherscan");
require("hardhat-deploy");
require("solidity-coverage");
require("hardhat-gas-reporter");
require("hardhat-contract-sizer");
require("dotenv").config();

And also your package.json file

{
  "devDependencies": {
    "@chainlink/contracts": "^0.6.1",
    "@nomiclabs/hardhat-ethers": "npm:hardhat-deploy-ethers",
    "@nomiclabs/hardhat-etherscan": "^3.1.6",
    "@nomiclabs/hardhat-waffle": "^2.0.5",
    "chai": "^4.3.7",
    "dotenv": "^16.0.3",
    "ethereum-waffle": "^4.0.9",
    "ethers": "5.7.2",
    "hardhat": "^2.12.7",
    "hardhat-contract-sizer": "^2.8.0",
    "hardhat-deploy": "^0.11.23",
    "hardhat-gas-reporter": "^1.0.9",
    "prettier": "^2.8.4",
    "prettier-plugin-solidity": "^1.1.2",
    "solhint": "^3.3.8",
    "solidity-coverage": "^0.8.2"
  },
  "dependencies": {
    "global": "^4.4.0",
    "hardhat-shorthand": "^1.0.0"
  }
}

So first delete node modules and yarn.lock and paste these in your package.json and run yarn install.

Along with that you need to refactor your deploy, test scripts according with ethers v5.
I was facing problems with v6, so I prefer to stay in v5.7.2.

It worked!! It was really a dependencies issue, not sure why the latest versions don't go well together, but I used these versions and it worked like a charm. Thanks for the help, really appreciate it.

Also can you do me a favor and tell me how do I know what versions to use in my projects in future. Like what version is compatible with one another and all.

[shikhar229169]

I just copy paste these dependencies which I mentioned above in package.json and do yarn install.
