BigNumber error

Question

I started learning solidity but when I use construct im getting the error, please help: here's the code

pragma solidity >=0.7.0 <0.9.0;

contract base{

    uint data;
    constructor (uint _data) public {
        data = _data;

    }
    function getData() public view returns(uint) {
        return data;
    }

}

Error - creation of Base errored: Error encoding arguments: Error: invalid BigNumber string (argument="value", value="", code=INVALID_ARGUMENT, version=bignumber/5.5.0)

Answer 1

Your contract works fine. As the two previous replies mentioned, you're "deploying" your contract with a void input. In other words, you haven't specified the value of your data.

type any uint value in "deploy" section and it will work fine.

All the best.

Answer 2

You need to input value when you deploy the contract.

Answer 3

The error is not on your smart contract, by the way, you're calling your constructor with "", try with numbers instead, e.g, "123", 123, 0...
