Hi, I am facing a problem with a very simple contract. Issue is that the contract is working fine in JVM but failing in testnet.

Hi! Can you share the code and to which network have you deployed it?

Code:

pragma solidity ^0.5.0;

contract carRegister{
struct car{
string liscence;
string color;
string brand;
string model;
uint256 serialNumber;
}

uint256 public totalCars = 0;
mapping(uint256 => car) public carSerialNumber;

function registerCar(string memory _liscence, string memory _color, string memory _brand, string memory _model) public{
totalCars++;
car memory newCar = car({
liscence: _liscence,
serialNumber: totalCars,
color: _color,
brand: _brand,
model: _model
});
carSerialNumber[totalCars] = newCar;
}
}

It was a private testnet that I deployed this code. Private testnet has same gas limit as that of mainnet. But I believe it will fail on rinkeby too.

Because the transaction was failing due to a revert operation being called when registerCar was invoked.

That piece of code does not have any revertable things. Everything is simple and direct

I haven't yet been able to find the cause of it.

@phantommlancer gonna go to bed now but I just run it here and had no issue

neither to the local JVM netiher to Rinkeby

Ohhh? Is it? I'll try on Rinkeby network then. I tried on private net. Maybe my private net doesn't have some upgrade.

Yeap it does work both in the local JVM and in Rinkeby Tesnet, so I would presume might be something strange going on in your private network 🙂

now time to sleep! Hope it helped!

I'll hope too it works 😃

Yeah, it works there :) nice

👍

@phantommlancer are you a student?

No, I graduated in 2017

Okay cool. Me 2016

What did you study?

Bachelors in Computer science and technology

and you?

Okay nice. Studied electrical and electronic engineering

Nice to meet you 🤝

Same here

👍

Yeah, exactly
