Hi,

I have built a chatbot using rasa stack, but I am not able to run multiple bot occurrence in a single rasa core instance as the bot gets confused and sends a wrong response to the users (sends User A’s response to User B and vice versa). I’ve read multiple blogs where using uuid was suggested as a solution to this problem but there was no clear explanation. Could you please let me know how to solve this problem. A code example would be much appreciated.

Hi @SudheshSolomon, thanks for posting your question. It depends on which input channels you’re using, defined in your `credentials.yml` file. For example, if your file contains the following:

```auto
rest:
 # you don't need to provide anything here - this channel doesn't
 # require any credentials

```

Then each user would need to send a HTTP POST request to `/base/webooks/rest/webhook` with the following JSON contents:

```json
{
    "message": "Hello",
    "sender": "abcd1234"
}

```

Where the `sender` needs to be **unique per user**. How you generate the `sender` value for each user is up to you, but it needs to be sent in each request sent to the Rasa instance. Using UUIDs is a valid option.

@fede. Thank you very much. This solution has given me an insight on how to proceed further 🙂

Hi @fede ,

Greetings. I tried the approach you suggested in creating the credentials file and parsing the chats as post request. However, I am stuck in the latter part. I am using flask to render HTML, but I am stuck at the point where I need to add an id to the user so that concurrent chats can happen simultaneously. Any help on how to proceed further is highly appreciated. NOTE: I am not able to parse my chat as GET/POST request. Kindly help me on this problem. My bot works perfectly fine if it is used only on one system. Also, I am not using slack, but I am using Flask and rendering the HTML.

When you render your HTML page with Flask, you could try including a unique ID somewhere in the page, so that each user that visits your site gets a unique ID assigned (you can also use Cookies for this). Would that help you?

Hi @fede,

Thanks for your reply. I am able to find that an uuid gets appended to the messages. 🙂

I am now able to run my bot in two systems but I get response from the server system and not from the client.

I have changed the ip address of rasa core to the ip of my server system and my core runs on the ip of my server as well. How do I get a response from both the systems.

NOTE: The issue of rendering flask in multiple system is fixed but now I am facing the issue where I get the response only from the server and not from the client machines.

Kindly help me in this.

Hi @fede,

I have fixed this issue as well and found out what needs to be changed but this has led to a new issue. The agent.py file generates new uuid for message.senderId for every message which is sent. How to keep the same sender id until the session is closed?
