Not getting the __callback() #100
Description
I have tried the code snippet provided in samples before and it worked. Also I tried my own contract with oraclized for GET and POST requests and it worked. But recently I noticed that the callback function is not being called in any of those previously worked samples.
I tried increasing the gas price upto 1000 GEWI for the callback and the result was the same.
I have been trying on Ropsten test network.
Following is a code snipped that is supposed to work, but does not receive a callback. I have imported the proper oraclized solidity file from a file and copied all the content from provable things github to that file.
`pragma solidity ^0.4.22;
import "./oracleService.sol";
contract ExampleContract is usingProvable {
string public ETHUSD;
event LogConstructorInitiated(string nextStep);
event LogPriceUpdated(string price);
event LogNewProvableQuery(string description);
function ExampleContract() payable {
provable_setCustomGasPrice(10000000000);
LogConstructorInitiated("Constructor was initiated. Call 'updatePrice()' to send the Provable Query.");
}
function __callback(bytes32 myid, string result) {
if (msg.sender != provable_cbAddress()) revert();
ETHUSD = result;
LogPriceUpdated(result);
}
function updatePrice() payable {
if (provable_getPrice("URL") > this.balance) {
LogNewProvableQuery("Provable query was NOT sent, please add some ETH to cover for the query fee");
} else {
LogNewProvableQuery("Provable query was sent, standing by for the answer..");
bytes32 queryId = provable_query("URL",
"json(https://www.therocktrading.com/api/ticker/BTCEUR).result.0.last");
}
}
}`
