Handler not found for handle name

I've got an application built with Actions Builder with webhook handlers hosted on the firebase side. As an application has been migrated from old bundle AOG + Dialogflow, fulfillment webhook was exposed in the next way:

    const functions = require('firebase-functions');
    const passport = require('passport');
    const express = require('express'); 
    const bodyParser = require('body-parser');
    const app = express();
    const fulfillment = require('../fulfillment');

    app.use(bodyParser.json());

    app.post('/', 
          async function(request, response) {
          await fulfillment(request, response);
        });

    exports.fulfillment = functions.https.onRequest(app);

Everything is working fine for both local and released production version, however, when Google team tries to reach a webhook endpoint, it throws a 500 error with a message: Handler not found for handle name. Full trace of an error is:

Error: Handler not found for handle name: 
at Function.handler (/workspace/node_modules/@assistant/conversation/dist/conversation/conversation.js:139:23)

Line 29 is await fulfillment, which is declared above, so it doesn't make a lot of sense. Have anybody else also experienced the same error, and how it can be solved? Any help appreciated.

It's hard to say for sure since you didn't post the contents of fulfillment but it also seems like 'handle name' is not defined. In Actions Builder, you have intents that are technically separate from the expected name that you'll receive in the webhook.

In the screenshot below, you specify "handler_name" as the handler you'll need in the webhook fulfillment.
