Cannot find module

Question

I’m following this tutorial to create a chatbot from the link below, and giving this error, can anyone help me with the error? the error is in the file server.js or in dialogflow.js?

dialogflow.js

const axios = require('axios')
const accessToken = process.env.DIALOGFLOW_ACCESS_TOKEN
const baseURL = 'https://api.dialogflow.com/v1/query?v=20150910'

module.exports = {

send (message) {

    const data = {
      query: message,
      lang: 'pt-BR',
      sessionId: '123456789!@#$%'
    }
    return axios.post(baseURL, data, {
      headers: { Authorization: `Bearer ${accessToken}` }
    })
  }
}

server.js

const express = require('express')
const bodyParser = require('body-parser')
const Pusher = require('pusher')
const cors = require('cors')
require('dotenv').config()
const shortId = require('shortid')
const dialogFlow = require('./dialogFlow')
const app = express()

app.use(cors())
app.use(bodyParser.urlencoded({ extended: false }))
app.use(bodyParser.json())

const pusher = new Pusher({
  appId: process.env.PUSHER_APP_ID,
  key: process.env.PUSHER_APP_KEY,
  secret: process.env.PUSHER_APP_SECRET,
  cluster: 'eu',
  encrypted: true
})

app.post('/message', async (req, res) => {
  // simulate actual db save with id and createdAt added
  console.log(req.body);

  const chat = {
    ...req.body,
    id: shortId.generate(),
    createdAt: new Date().toISOString()
  }

  //update pusher listeners

  pusher.trigger('chat-bot', 'chat', chat)

  const message = chat.message;
  const response = await dialogFlow.send(message);

  // trigger this update to our pushers listeners

  pusher.trigger('chat-bot', 'chat', {
    message: `${response.data.result.fulfillment.speech}`,
    type : 'bot',
    createdAt : new Date().toISOString(),
    id: shortId.generate()
  })

  res.send(chat)
})

app.listen(process.env.PORT || 5000, () => console.log('Listening at 5000'))

Answer 1

By what was reported the file name is dialogflow.js and you are importing dialogFlow. Use the require in the following way, if the files are in the same folder:

const dialogFlow = require('./dialogflow');
