From user perspective, even a simple interaction such as clicking on "I have new issue / problem" will result in this interaction, stating "Relationships and cryptic text are the only two things I am not good at, how about we try again!"
Cause
Issue is specific to using rasa release 1.8.3. As a result of the introduction of this release of Rasa, the backend scripts in the casm bot directory need to be updated.
Environment
Release : 17.3
Component : SERVICE DESK MANAGER
Resolution
- Stop the Aria ChatBot by closing out the Anaconda Command Prompt instance.
- Access the "casm-bot" directory where you have the Aria Chatbot installed.
- Backup the "actions" directory under the "casm-bot" directory. We advise copying the entire "actions" directory into a separate folder rather than right click/copy/paste the "actions" directory, creating an "actions - Copy" directory under "casm-bot" directory.
- Under the "actions" directory inside the casm-bot, replace the string “rasa_core_sdk” with “rasa_sdk” in all the files. Save the files when done.
The easiest way to achieve this is to open all of the files in the "actions" directory in Notepad or Notepad ++ and do a Replace action, changing all references to string “rasa_core_sdk” with “rasa_sdk” - Start a new Anaconda Command Prompt and restart Aria Chatbot:
cd to the Aria directory
Run ".\botenv\Scripts\activate"
cd to the casm-bot directory
Run "rasa_train", then "rasa_run"
Subsequent interactions will look like this (correct):
