Bot Service is not working with Node.js . Error cannot find module 'botbuilder'

Question

I created a Bot Service through 'Azure Portal' with Node.js and LUIS. When the Bot is created, i can see the 'Chat interface' loading forever with a message 'Loading chat interface'. Bot developer interface

So I opened Bot through 'My bots' in 'dev.botframework.com' and tested the connection. It failed with the below error. Bot chat window

When i pinged 'Hi' in the chat box there, i could see the error in the logs 'Exception while executing function: Functions.messages. mscorlib: Error: Cannot find module 'botbuilder'

I could see 'botbuildr' dependency in 'package.json' as below.

{
  "name": "luisbot",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "dependencies": {
    "botbuilder": "^3.7.0",
    "botbuilder-azure": "3.0.2"
  },
  "devDependencies": {
      "restify": "^4.3.0"
  },  
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "",
  "license": "ISC"
}

Any suggestions for the error?

I had this same problem and solved it by running npm install in kudu console.

Go to your Bot Service's Settings-tab and click to open "Advanced settings". There you can find "Advanced Tools" (kudu) under Development tools. Open Debug Console and cd to the folder where you have package.json (for me it was D:\home\site\wwwroot\messages) and run npm install.

After that you can communicate with the bot in dev.botframework.com although the chat interface won't still work in Azure portal.
