React based chatroom for a chatbot using - scalableminds/chatroom

React based chatroom for a chatbot using :

I am trying to add the ‘WEATHER BOT’ to a website. (Or sample HTML) page. I used the steps given in Advanced Usage with a custom Rasa Core project as Custom Channel from Python .

Following is the code I ran (‘’) after executing the previous steps suggested in the page (i.e. Steps under Basic Usage - Running build and HTML page for your Chatroom)

    import os
    from rasa_core.channels import HttpInputChannel
    from rasa_core.agent import Agent
    from rasa_core.interpreter import RasaNLUInterpreter
    from rasa_slack_connector import SlackInput
    from bot_server_channel import BotServerInputChannel

    # Creating the Interpreter and Agent
    def load_agent(): 
        nlu_interpreter = RasaNLUInterpreter('./models/nlu/default/productnlu')
        agent = Agent.load('./models/dialogue', interpreter = nlu_interpreter)

    # Creating the server
    def main_server():
        agent = load_agent()

        channel = BotServerInputChannel(agent, port=cmdline_args.port)
        agent.handle_channels([channel], http_port=cmdline_args.port)


Got the following error:

    Traceback (most recent call last):
      File "", line 26, in <module>
      File "", line 23, in main_server
        channel = BotServerInputChannel(agent, port=cmdline_args.port)
    NameError: name 'cmdline_args' is not defined

Changed the port to 5005 in the following line

channel = BotServerInputChannel(agent, port=cmdline_args.port)

Different issue as it occurred in the same code line after changing the port number. Got error @ agent.handle_channels([channel], http_port=5005)

Traceback (most recent call last):
  File "", line 23, in <module>
  File "", line 21, in main_server
    agent.handle_channels([channel], http_port=5005)
AttributeError: 'NoneType' object has no attribute 'handle_channels'

Are you sure the agent loaded properly?

Yes @akelad. I think there is a version incompatibility with RASA core and the widget. I am still trying to update to the RASA core version and debug.

@vishnuragas are you able to resolve the error?

the same thing happening to me

@vishnuragas in order to use this script, I tried to start chatroom (yarn serve) > action server> then, but I can’t run the command though because it says port 5005 has been used. Do you know how to solve this issue?

Continuing the discussion from React based chatroom for a chatbot using - scalableminds/chatroom:

Hello Friend, I have just cloned chatroom github repo and tried running it.I m getting this error.Please let me know how to fix it.

Basically my main aim is to integrate my rasa with UI interface which take text and voice, both as input.I am stuck with this UI getting ./dist/chatroom.css not found.

step i used to run this repo:

yarn build
yarn watch
yarn serve
Open http://localhost:8080/index.html in my browser
