乙太坊橋 - 觸髮帶有合約 myid 的 WARN 日誌，但之前已經看到，跳過事件

我正在使用帶有 nodejs 的 ganache 桌面應用程序，我需要通過 ethereum-bridge 從 API 獲取值。

以下是合約程式碼 -

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");
    throw;
}
Log("Entered callback function");
Log(result);
energy = parseInt(result, 2);

}


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

在 ethereum-bridge 控制台中，我收到了event is skipped的警告。

node bridge -H localhost:7545 -a 5

當我清除文件夾中的CallbackTxs文件和 Queries文件時ethereum-bridge-master/database/tingodb，Apicall 成功執行。只需要清除以前的日誌資訊，因為為 event 生成的myid已經在 db 文件中。
