Cannot Estimate Gas

[dhwanilTrojanpy]

I am trying to deploy the SimpleStorage contract from FactoryStorage Contract. In the tutorial, we are deploying it on Ethereum. As we have already deployed it on the zkSync, I am trying to deploy it on the zkSync as well. when I try to make a transaction by clicking on FactoryStorage, It gives me the below error.

Error in function invocation (message): "cannot estimate gas; transaction may fail or may require manual gas limit [ See: https://links.ethers.org/v5-errors-UNPREDICTABLE_GAS_LIMIT ] (reason=\"execution reverted\", method=\"estimateGas\", transaction={\"from\":\"0xac6796E373Ef3D2BC7C2E76C8a1660C0A9a38A50\",\"to\":\"0xFacD19392FB16C2acdBbc8A94c3FDa8AFd00Be56\",\"data\":\"0x1dda6541\",\"type\":0,\"accessList\":null}, error={\"code\":-32603,\"message\":\"Internal JSON-RPC error.\",\"data\":{\"code\":3,\"message\":\"execution reverted\",\"data\":\"0x3e5efef9010000a12e27ba1bd30bb4afd017e30038c36960f562edcff70bbf5ff696dfec\",\"cause\":null},\"stack\":\"{\\n \\\"code\\\": -32603,\\n \\\"message\\\": \\\"Internal JSON-RPC error.\\\",\\n \\\"data\\\": {\\n \\\"code\\\": 3,\\n \\\"message\\\": \\\"execution reverted\\\",\\n \\\"data\\\": \\\"0x3e5efef9010000a12e27ba1bd30bb4afd017e30038c36960f562edcff70bbf5ff696dfec\\\",\\n \\\"cause\\\": null\\n },\\n \\\"stack\\\": \\\"Error: Internal JSON-RPC error.\\\\n at new o (chrome-extension://nkbihfbeogaeaoehlefnkodbefgpgknn/common-1.js:1:653344)\\\\n at a (chrome-extension://nkbihfbeogaeaoehlefnkodbefgpgknn/common-1.js:1:656577)\\\\n at Object.internal (chrome-extension://nkbihfbeogaeaoehlefnkodbefgpgknn/common-1.js:1:657186)\\\\n at c (chrome-extension://nkbihfbeogaeaoehlefnkodbefgpgknn/common-1.js:1:398667)\\\\n at chrome-extension://nkbihfbeogaeaoehlefnkodbefgpgknn/common-1.js:1:399669\\\\n at async chrome-extension://nkbihfbeogaeaoehlefnkodbefgpgknn/common-1.js:1:648682\\\"\\n}\\n at new o (chrome-extension://nkbihfbeogaeaoehlefnkodbefgpgknn/common-1.js:1:653344)\\n at a (chrome-extension://nkbihfbeogaeaoehlefnkodbefgpgknn/common-1.js:1:656577)\\n at Object.internal (chrome-extension://nkbihfbeogaeaoehlefnkodbefgpgknn/common-1.js:1:657186)\\n at c (chrome-extension://nkbihfbeogaeaoehlefnkodbefgpgknn/common-1.js:1:398667)\\n at chrome-extension://nkbihfbeogaeaoehlefnkodbefgpgknn/common-1.js:1:399669\\n at async chrome-extension://nkbihfbeogaeaoehlefnkodbefgpgknn/common-1.js:1:648682\"}, code=UNPREDICTABLE_GAS_LIMIT, version=providers/5.7.2)"

As far as I understood, it tells me to define the gas limit manually. I tried to research it but couldn't find the exact solution. Please help me find the solution. I am pasting my code link below.

// bool hasFavouriteNumber = false;

    uint256 public MyfavouriteNumber;
    struct Person {
        string name;
        uint256 _favouriteNumber;
    }
    Person[] public listOfPeople;
    mapping(string => uint256) public nameToFavouriteNumber;

    function store(uint256 _favouriteNumber) public {
        MyfavouriteNumber = _favouriteNumber;
    }

    // view - modifier can only read the state variable but cant modify it
    // pure- this modifier cannot read or update the stae variable. It is for separate computation.
    function retrive() public view returns(uint256){
        return MyfavouriteNumber;
    }

    function addPeopleArray(string memory _name, uint256 _favouriteNumber) public {
            listOfPeople.push(Person(_name, _favouriteNumber));
            nameToFavouriteNumber[_name] = _favouriteNumber;
    }

}
contract StorageFactory{
SimpleStorage public simpleStorage;

function createSimpleStorageContract() public {
simpleStorage = new SimpleStorage();

}

}`

Hello @dhwanilTrojanpy, Did Patrick deploy and use StorageFactory on the ZKSync network? If yes, please share the link to the lesson for a refresher.

Hi @EngrPips. NO Patric did not deploy it using zkSync Network. I just wanted to try it on my own.

Oh, I see. ZKsync is architecturally different from the EVM, so some things can work correctly on the EVM and not work on ZKsync. Maybe using a factory contract is one of those.
