我已经编写了云函数，它发送状态码为200或400的响应，但有时我会收到以下错误

函数执行耗时219毫秒，已完成，状态为：'connection error‘错误:函数崩溃超出请求范围，函数调用中断。

所以问题是我需要知道发送这个错误消息和一些状态码作为云函数的响应。

const functions = require('firebase-functions');
const dialogflow = require('dialogflow');
const admin = require('firebase-admin');
const Firestore = require('@google-cloud/firestore');
const firestore = new Firestore();
admin.initializeApp();
var db = admin.firestore();
const {WebhookClient} = require('dialogflow-fulfillment');
var UID = new Object();

exports.fulfillmenttext = functions.https.onRequest((req,res) =>{ 
    const answer1 = req.body.Text;
    const uid = answer1.substring(0,28);
    const answer = answer1.substring(28);
    const sessionId = uid;
    var count,questvalue;
    const promise = db.collection("***").doc('***').collection("**").doc("uid").get();
    promise.then(doc => {
        snapshot.forEach(function(doc) {
            if (doc.exists) {
              count = doc.data().count;
                if(count == 1){
                    var updatequest = title[questvalue];
                    res.status(200).send({"question":updatequest,"question_number":questvalue});
                    return;
              }
              else{
                runSample();
              }
          } 
          else {
              console.log("No such document!");
          }
        });
      }).catch(function(error) {
          console.log("Error getting document:", error);
      });


    async function runSample() {

      //Instantiate a DialogFlow client.
      const dialogflow = require('dialogflow');
      const sessionClient = new dialogflow.SessionsClient({
        projectId,
        credentials,
      });
    // Define session path
      const sessionPath = sessionClient.sessionPath(projectId, sessionId);
      // The text query request.

        const request = {
            //session: context1,
            session: sessionPath,
            queryInput: {
              text: {
                text: answer,
                languageCode,
              },
            },
        };

      const responses =  await sessionClient.detectIntent(request);
      const result = responses[0].queryResult;
      let action = result.action; 
      if (result.intent) {
        const question = result.fulfillmentText;
        console.log("question is",question);
        const actionHandlers = {
            'early': () => {
                console.log('earlyaction1', action);
                let name1 = JSON.stringify(result.parameters.fields.Name.stringValue);
                name1 = name1.toString().replace(/"/g,"");
                var data1 = {
                    Name: name1
                };
                var setDoc1 = admin.firestore().collection('**').doc('uid').collection("***").doc('uid').collection('**').doc('**').update(data1);


            },

        };
        if (action === 'early') {
             console.log('1');
             actionHandlers[action]();
        }


        res.status(200).send({"question":result.fulfillmentText,"action":action,"question_number":title.indexOf(question)});
        } else {
          console.log(`  No intent matched.`);
          res.status(400).send({"action":"empty"});
      }
    } 

});
