How to integrate Dialogflow API v2 with MS BotFramework using dialogflow-nodejs-client-v2

I am building a bot using MS BotFramework functions and I am trying to use Dialogflow with MS BotFramework but I am failing with setting up configuration. dialogflow-nodejs-client-v2 library requires that GOOGLE_APPLICATION_CREDENTIALS environment variable is set. Which I believe I set :

I've also manually uploaded conf file into the, what I believe is the working directory

enter image description here

Yet bot is still failing. I tried various paths as value of a variable including absolute path : D:\home\site\wwwroot\messages\test-0691d01dae88.json

still with no luck.

Error I am getting is very cryptic :

Exception while executing function: Functions.messages. mscorlib: One or more errors occurred. Error: package.json does not exist at D:\home\site\wwwroot\package.json
at Object.module.exports.exports.find (D:\home\site\wwwroot\.funcpack\index.js:272715:15)
at Object.module.exports.exports.status.OK (D:\home\site\wwwroot\.funcpack\index.js:51739:12)

at Object.<anonymous> (D:\home\site\wwwroot\.funcpack\index.js:260961:14)
at __webpack_require__ (D:\home\site\wwwroot\.funcpack\index.js:21:30)
at new GrpcClient (D:\home\site\wwwroot\.funcpack\index.js:132359:25).

It suggest package.json is missing but this error only occurs if I try to use dialog flow to be specific I require recognizer.js file in index.js. 

var apiairecognizer_v2 = require('./recognizer');

It's content is : 

"use strict";
const dialogflow = require('dialogflow').v2beta1;
const uuid = require('uuid');
// next line causes error 
const sessionClient = new dialogflow.SessionsClient();

var ApiAiRecognizer = function(){
};

ApiAiRecognizer.prototype.recognize = function (context, done){
}

module.exports = ApiAiRecognizer;

Commenting out sessionClient line will make bot work.

Any idea how to configure Dialogflow v2 with MS BotFramework functions?

thanks

Error seems straight forward for any node.js application. You are using statement:

var apiairecognizer_v2 = require('./recognizer');

So application is expecting package.json file for installing packages like:

{
  "name": "abc",
  "devDependencies": {
     "dialogflow":"^0.6.0",
     "uuid":"^3.3.2",
     "recognizer":"^0.0.2"
  }
}

it is used for installing package by npm.

Error is that it is expecting package.json with all referenced & dependent packages there in location D:\home\site\wwwroot\package.json

You can either manually add that or try going to that folder if node is installed & npm is used, try 

npm install --save recognizer

or

npm install --save-dev recognizer

it will save latest package in package.json.

It seems you are already getting two packages dialogflow & uuid resolved using npm without error so issue is missing recognizer entry in package.json. Try adding package in package.json there.
