Problems with Aria virtual analyst chatbot in SDM 17.3

  • 1.  Problems with Aria virtual analyst chatbot in SDM 17.3

    Posted Sep 09, 2020 10:44 AM
    Hello Community,

    currently i am trying to implement the Aria virtual analyst in 17.3.
    I have modified the nlu.md file like described in the documentation (added some real ticket numbers, modified the regex) and trained the model using rasa_train.

    The first thing i want to try is to "list my tickets" and get the status of a specific ticket.
    The problem is that during the conversation Aria forgets the ticket entity like you can see in the screenshot and the log entries.
    In the aria console i can see that aria was able to extract the entity but lost the entity when it comes to the intent "get_tkt_status".
    There are also some errors i have marked in red.

    Do you have faced some similar problems or do you have any tipps for me?
    Many thanks in advance for your help.

    Sebastian
