lambda-local -l index.js -h handler -e holiq.js

holiq.js没有错误事件输出正确，mongodb成功连接，但

错误：结束-错误：
error: { "errorMessage": "Task timed out after 5.00 seconds", "errorType": "TimeoutError", "stackTrace": [ "Context.<anonymous> (/usr/local/lib/node_modules/lambda-local/lib/context.js:127:9)", "ontimeout (timers.js:436:11)", "tryOnTimeout (timers.js:300:5)", "listOnTimeout (timers.js:263:5)", "Timer.processTimers (timers.js:223:10)" ] }

发生超时错误请帮帮我！〜

我认为只需一个$set即可用于更新

collection.updateOne(
      { a: a },
      { $set: { b: b,e: e, c: c, d: d } },
      function(err, result) {
        assert.equal(err, null);
        assert.equal(1, result.modifiedCount)
        console.log("Updated the document for " + a);
        callback(result);
      }
    );

将lambda执行时间增加到10 secs，以查看其超时问题或代码执行错误。
