大家好，我尝试在 Meteor中使用proxy-verifier NPM 包，如下所示：

import ProxyVerifier from 'proxy-verifier';

// this is my method call on server startup
Jobs.find().forEach((job) => {
 Meteor.call("checkProxy", job.proxy, (error, result) => {
  if (error) {
   console.log("error: " + error);
  } else {
   console.log("result: " + result); // result is true or false
   let inc;
   inc = result ? 1 : -1;
   Jobs.update({
    _id: job._id
   }, {
    $inc: {
     count: inc
    }
   });
  }
 });
});

// this is my method
checkProxy(proxy) {
 this.unblock();

 let syncTestProtocol = Meteor.wrapAsync(ProxyVerifier.testProtocol);
 let testResult;
 try {
  testResult = syncTestProtocol(proxy);
  return testResult.ok;
 } catch (error) {
  return false;
 }
}

它运行良好，但有时（可能在检查某些代理时）它会返回以下异常：

I20160724-07:48:18.391(4.5)? Exception in callback of async function: Error: Future resolved more than once

我使用Meteor.wrapAsync的checkProxy方法与此有关吗？请指导我如何查找和解决此问题。
