Agent Resource type returns null in Dialogflow Fulfilment

[nidhinkumar06]

I have used cloud functions for my action. Based on the agent resource type, I am sending the response back. As per the guidelines provided in the document i have changed the Twilio integration. After deployment when i check the agent.requestSource type it returns null. Earlier it returns 'twilio' or 'GOOGLE_ASSISTANT' but now it returns null.

Implementation Code

exports.dialogflowFirebaseFulfillment = functions.https.onRequest(
  (request, response) => {
    console.log("Dialogflow Request body: ", request.body);
    const agent = new WebhookClient({ request, response });
    console.log("agent originalRequest", agent.originalRequest);
    console.log("Agent resource", agent.requestSource);
    const conv = agent.conv();
    let sender;
    let receiver;

    if (agent.requestSource === "twilio") {
      const requestBody = request.body;
      sender = requestBody.originalDetectIntentRequest.payload.data.From;
      receiver = requestBody.originalDetectIntentRequest.payload.data.To;
    }

I have added the source in the request body like below and now it works fine

let body = req.body;
body.source = 'twilio';
