Chat window doesn't work "Waiting for server". Early version doesn't return answers.

I still getting “Waiting for server…” and can’t type anything.

Please, help me configure Rasa X and Rasa-Webchat to interact with each other.

Config:

socketio:
  user_message_evt: user_uttered
  bot_message_evt: bot_uttered
  session_persistence: false

Changing session_persistence to true doesn’t do anything.

Changing webchat’s version to 0.4.1 allows to type messages but rasa backend still doesn’t accept anything.

Using rest api channel with another webchat repository works.

Ok, your problem is because is because engineio has been updated and requires now an explicit CORS directive. You can see how we do it for Botfront: https://github.com/botfront/rasa-addons/blob/c82ac585c028b76e87580ee18ec6e815d719b088/rasa_addons/core/channels/webchat.py#L148

Here is my config.yml file

Configuration for Rasa NLU.

https://rasa.com/docs/rasa/nlu/components/

language: en pipeline: supervised_embeddings

Configuration for Rasa Core.

https://rasa.com/docs/rasa/core/policies/

policies:

• name: “KerasPolicy” featurizer:
  • name: MaxHistoryTrackerFeaturizer max_history: 5 state_featurizer:
    • name: BinarySingleStateFeaturizer
• name: “MemoizationPolicy” max_history: 5
• name: “FallbackPolicy” nlu_threshold: 0.4 core_threshold: 0.3 fallback_action_name: “utter_default”

When training the core getting "Object of type ‘MaxHistoryTrackerFeaturizer’ is not JSON serializable’
