The code i use to run the server is:

python -m rasa_core.run --port 5002 --enable_api -d models/core/xonebot -u models/nlu/default/xonebot --endpoints endpoints.yml --credentials credentials.yml --debug

What did you send as request?

5

with postman i send that:

{ “sender”: “Rasa”, “text”: “Hola” }

to localhost addres:

http://localhost:5002/webhooks/rest/webhook

6

send message instead of text in your request.json

{ “sender”: “Rasa”, “message”: “Hola” }

Hi, @souvikg10, I am accessing my RASA server from the front end as you have suggested. The message goes something like this: { “sender”: “Rasa”, “message”: “Hi there!” } But, after few hits I am getting the following error: if message.text.startswith(INTENT_MESSAGE_PREFIX): AttributeError: ‘NoneType’ object has no attribute ‘startswith’ and henceforth the bot doesn’t work as expected

I think it has something to do with the escape sequence. What is the message you are sending?

is it some payload with intent prefixed with /

The object sent is None from the front end most likely due to wrong JSON notation. Check the console log of what is being sent to the server as a request

Thank you so much for the prompt reply @souvikg10. Yes, I have some buttons and on clicking it it will be returning the payload prefixed with / and will be setting a slot value as well.

As you suggested I removed it and tried. Now an extra character " is being send to the server on clicking the button which leads to wrong responses. Any thoughts on that?
