Rasa Chatbot cannot response to user input

Question

I have using DIETClassifier for my entity extraction, and this is my pipeline:

pipeline:
  - name: SpacyNLP
    model: en_core_web_sm
  - name: SpacyTokenizer
  - name: CountVectorsFeaturizer
  - name: CRFEntityExtractor
  - name: DIETClassifier
    epochs: 200
    random_seed: 2

and this is example of intents that I have with entities in the nlu file:

version: "2.0"

However, when I train my chatbot with rasa train command, and I tested it with rasa shell command, it gives only a response with the first input from the user(me) and then the responses stopped working! I am finding of the error and the solution for 2 weeks and I did not find it, this is an example:

can someone help me? or if I have any errors in my files that I mentioned above can someone tell me what is the errors? I followed the rasa documentation for the domain files and how to define the entities in the intents but I faced this problem, and all the explanasion I found on the internet is not with rasa 2.0 so I cannot know what is the problem

However, when I remove the entities form the domain file It has responses! but it is being like that:

it says add the entities to the domain file, and as I showed you before when I added them the responses stop working

Answer 1

Unless the domain file does not show all the responses in your actual domain file, then your problem is that you haven't provided response text for most responses in your stories. You may have removed these accidentally when adding the entities.
