When i try to deploy my example contract it gives me the error creation of Auction errored: Error encoding arguments: Error: invalid BigNumber string (argument="value", value="", code=INVALID_ARGUMENT, version=bignumber/5.0.8)
// SPDX-License-Identifier: GPL-3.0
pragma solidity ^0.5.2;
contract Auction{
mapping(address=> uint)public bids;
struct Car{
string description;
uint value;
uint built_year;
}
Car public private_car;
mapping(address=> Car) public cars;
constructor(string memory _description, uint _value, uint _built_year) public{
private_car.description = _description;
private_car.value = _value;
private_car.built_year = _built_year;
cars[msg.sender] = private_car;
}
function bid() payable public{
bids[msg.sender] = msg.value;
}
}
Why it gives this error when i pass nothing in the constructor? It works fine if i pass something in the constructor at the time of deployment.
