对话中的google actions sdk第二个请求失败,返回“typeerror:standard不是函数”

我正在使用actions sdk v2库构建一个google操作。

当我使用简单的conv.ask和conv.close方法时,我能够使对话起作用。但是,当我向处理链中添加异步方法时,我就面临问题。我正在使用

"actions-on-google": "^2.4.1", 
"firebase-admin": "^6.0.0",
"firebase-functions": "^2.1.0",

在每三次失败的尝试之后,第四次尝试就通过了。看起来上一个请求占用了我的firebase云功能!

对实现的第一个请求工作得很好,随后的请求失败,并显示“typeerror:standard不是google/dist/framework/express.js上的/srv/node_modules/actions的函数”

severity:  "ERROR"  
 textPayload:  "TypeError: standard is not a function
    at /srv/node_modules/actions-on-google/dist/framework/express.js:27:13
    at omni (/srv/node_modules/actions-on-google/dist/assistant.js:44:53)
    at cloudFunction (/srv/node_modules/firebase-functions/lib/providers/https.js:57:9)

    at _combinedTickCallback (internal/process/next_tick.js:131:7)
    at process._tickDomainCallback (internal/process/next_tick.js:218:9)" 

我知道,当处理链中有异步函数时,应该将promise返回给intent处理程序。我正在做。但随后的请求仍然失败。

const app = actionssdk();
 // ... app code here


  app.middleware((conv) => {
    console.log('Conversation in Middleware:', conv);
    conv.hasScreen =
      conv.surface.capabilities.has('actions.capability.SCREEN_OUTPUT');
    conv.hasAudioPlayback =
      conv.surface.capabilities.has('actions.capability.AUDIO_OUTPUT');
  });

// Welcome Intent
app.intent('actions.intent.MAIN', (conv, input) => {
  // conv.ask('How are you');
  console.log('Conversation: ' + JSON.stringify(conv), conv);
  console.log('actions.intent.MAIN', input)
  return new Promise((resolve, reject) => {
    processIntents({conv: conv, input:input}).then(r => {
      console.log('Passing response from the handler!', r);
      for(let a of r) {
        conv.ask(a);
      }
      resolve();
    }).catch(e => reject(e));
  });
});

// React to a text intent
app.intent('actions.intent.TEXT', (conv, input) => {
  console.log('actions.intent.TEXT', input)
  // conv.ask('How are you');
  console.log('Conversation: ' + JSON.stringify(conv), conv);
  console.log('actions.intent.TEXT', input)
  return new Promise((resolve, reject) => {
    processIntents({conv: conv, input:input}).then(r => {
      console.log('Passing response from the handler!', r);
      for(let a of r) {
        conv.ask(a);
      }
      resolve();
    }).catch(e => reject(e));
  });
});

// React to list or carousel selection
app.intent('actions.intent.OPTION', (conv, params, option) => {
  // conv.ask('How are you');
  console.log('actions.intent.OPTION', {input: conv.input, option: option, params:params})
  console.log('Conversation: ' + JSON.stringify(conv), conv);
  console.log('actions.intent.OPTION', option)
  return new Promise((resolve, reject) => {
    processIntents({conv: conv, params: params, option: option}).then(r => {
      console.log('Passing response from the handler!', r);
      for(let a of r) {
        conv.ask(a);
      }
      resolve();
    }).catch(e => reject(e));
  });
});
app.intent('', (conv) => {
  // conv.ask('How are you');
  console.log('Empty Intent for direct WEB requests / ALEXA requests', conv);
  let input = ((conv.request.originalRequest ||{}).result ||{}).resolvedQuery;
  return new Promise((resolve, reject) => {
    processIntents({conv: conv, input: input}).then(r => {
      //TODO: send raw HTTP Response
      //TODO: Yet to figure out how this can be done@!
      resolve();
    }).catch(e => reject(e));
  });
});

const processIntents = (args) => {
    let conv = args["conv"];
    let params = args["params"];
    let option = args["option"];
    let input = args["input"];
    // Async Function here that responds with a Promise
    // Based on the request, it will send either array of responses to use in conv.ask calls
   // OR send response JSON body that can be sent to Amazon Alexa / WEB requests
  return Promise.resolve(response);
}
exports.apiaifns = functions.https.onRequest(app);

我正在发送来自 processIntents 方法并在响应时遍历数组。

我已经尝试了很多可能的排列和组合,但是仍然没有成功。

更新:使用google云函数而不是firebase的gcf进行测试 更新了我的应用程序代码,使其成为一个快速应用程序,并以相同的名称部署到gcfs。现在情况是 更糟的 . 只有云功能部署后的第一个请求成功,所有后续请求失败,错误与之前相同!

以下是我对函数的更新:

const express = require('express')
const bodyParser = require('body-parser')
var morgan = require('morgan')
.
.
.
const expressApp = express().use(bodyParser.json())
expressApp.use(morgan('dev'))
expressApp.post('/fulfillment', app)

exports.apiaifns = expressApp;

我还将actio调用url更改为“ https://us-central1-my-project.cloudfunctions.net/apiaifns/fulfillment “

这简直把我逼疯了,我找不到问题的原因!请帮助。
