Hi, I have built a flow and I executed it on the UI using socket.io channel. At initialization the bot automatically encounters some random intent and respond accordingly.
Below is the snapshot:
Here the bot is giving a response without any user input.
I believe this particular UI sends a message when the UI is opened. you should turn that off in the code of the application or specify the intent you want to start with (e.g. greeting)
Yeah thanks @Remy. I will look into that and get back to you. 
Get back to me if it worked!
Yeah @Remy it worked for mrbot-ai/ rasa-webchat. Now it’s not giving me any initial message.
In my index.html file I commented this line:
//initPayload: "/get_started",
Good stuff! Now if you want to open with a ‘hello’ or something, just uncomment that and make the payload “/hello”
Yeah I did that But it’s not working for payload /hello. So where do we define this payload?
The payload described in the index is just an intent that gets sent with 100% confidence. For instance, if I’d want the chatbot to open with ‘hi there’ I define my stories as:
## initialize
* hello
- utter_hi
Then put the intent ‘hello’ in your domain file.
Then change the index.html payload to /hello
Thank you very much @Remy. It is working fine. Thanks for the solution pal.
