Hi Team,

For the first time when there are no matching topics are available for user utterance,

it is going to fallback topic and from there we are returning a question.

When user post same question for the second time, it is not going to Fallback topic. [Why it is not going to Fallback System Topic]

When user post same question for the third time, it is going to Fallback topic.

System Fallback topic is not getting executing if we return question for earlier user query.

Can you please help me on this?

After Replacing basic card with Adaptive card, it is working as expected.

Re: System Fallback topic is not executing if there are no matching topics for the user query or utterance.

So your question was: "When user post same question for the second time, it is not going to Fallback topic. [Why it is not going to Fallback System Topic]"

Based on your Fallback topic, this is an expected behavior. The system takes "same question" from the user as the answer for the asked question. If you want to execute the Fallback topic again, you can add the condition that check the output variable and then use "Go to step" node to redirect to the first node in the topic (in this case System.FallbackCount won't be incremented, so you might want to introduce a new variable)

Hi Robulane,

Thank you so much for quick reply, appreciated.
Below is the fallback code.

Re: System Fallback topic is not executing if there are no matching topics for the user query or utterance.

It's possible that the second user's input is considered the answer to the question. It will help if you provide the code of your fallback topic. You can open Code Editor and copy and paste yaml here.
