Looks like flow ran successfully but still last component - Return values to Power Virtual Agents have some issue, kindly look in to it and let me know how to tackle this one.

Hi @naveens1,

 

Can you open your flow in edit mode and show/share a screenshot of the configuration you have in the Apply to each action and the return value to PVA action?



Happy to help out! 🙂

body('HTTP')?['answers']    ----Apply to each
items('Apply_to_each')?['answer']   -------Set variable
items('Apply_to_each)?['Score']    -------Set variable2
variable('Score')   -------Condition
variable('QnAAnswer')   ---------Return values to Power Virtual Agents

Let say I created custom qna in language studio then how to integrate this in to Power Virtual Agents?

Do you have any documentation/link, if so please share.

 

Thanks,
