I am using ganache desktop application with nodejs where, I need to fetch values from API via ethereum-bridge.

Following is contract code -

pragma solidity ^0.4.4;

import "./usingOraclize.sol";

contract BondRegister is usingOraclize {

uint public energy;

event Log(string text);

function BondRegister() {

 Log("Contract created");
 OAR = OraclizeAddrResolverI(0x6f485C8BF6fc43eA212E93BBF8ce046C7f1cb475);

function getCall() payable returns(bool success) {

 oraclize_query("URL", "json(https://min-api.cryptocompare.com/data/price?fsym=ETH&tsyms=USD).USD");

function __callback(bytes32 _myid,string result) {

if (msg.sender != oraclize_cbAddress()) { 
     Log("thrown error");
Log("Entered callback function");
energy = parseInt(result, 2);


function getenergy() returns (uint) {
return energy;

In ethereum-bridge console I'm getting a warning that event is skipped.

 node bridge -H localhost:7545 -a 5

Please add this line to your contract constructor:

OAR = OraclizeAddrResolverI(0x6f485C8BF6fc43eA212E93BBF8ce046C7f1cb475);

When I cleared CallbackTxs file and Queries file in ethereum-bridge-master/database/tingodb folder, Apicall executed successfully. Just need to clear previous log information since myid generated for event was already in db files.
