hi, I m trying to run example project on remix and I m getting this error. I couldnt find solution for that. any idea how to solve it?
code is
pragma solidity ^0.8.17;
import "https://github.com/provable-things/ethereum-api/blob/master/contracts/solc-v0.8.x/provableAPI.sol";
contract DieselPrice is usingProvable {
uint public dieselPriceUSD;
event LogNewDieselPrice(string price);
event LogNewProvableQuery(string description);
constructor() payable{
update();
}
function __callback(
bytes32 _myid,
string memory _result
)
public
{
require(msg.sender == provable_cbAddress());
emit LogNewDieselPrice(_result);
dieselPriceUSD = parseInt(_result, 2); // Let's save it as cents...
// Now do something with the USD Diesel price...
}
function update()
public
payable
{
emit LogNewProvableQuery("Provable query was sent, standing by for the answer...");
provable_query("URL", "xml(https://www.fueleconomy.gov/ws/rest/fuelprices).fuelPrices.diesel");
}
}
when I try to deploy it gives error below
[vm]from: 0x5B3...eddC4to: DieselPrice.(constructor)value: 0 weidata: 0x608...3656clogs: 0hash: 0xed5...e5fbb
creation of DieselPrice errored: VM error: revert.
revert
The transaction has been reverted to the initial state.
Note: The called function should be payable if you send value and the value you send should be less than your current balance.
Debug the transaction to get more information.
Thanks
