Hi,
I`m currently running a POC using a chatbot for ms teams powered by copilot studio. This chatbot has acces to a determined knowledge source and must answer technical questions based on those documents.
I am using gpt 5 with reasoning as model, I have disabled web search and general knowledge.
I also disabled all the topics, as it was just useless for me, as I dont intend on putting a human on the loop at least for now. However, even after disabling the topics, I keep getting the message:
"Sorry, I am not able to find a related topic. Can you rephrase and try again?"
Fact is that I dont want it to use any topic at all, and thats why I disabled all of them. I just want it to answers the users questions based on the provided knowledge and instructions.
I noticed that this only happens when a user sends the same questions more than 2 times, and that this would be a fallback trigger. But even after disabling it and publising a new version, this topic keeps being triggered.
This is causing me a huge problem during the POC, as the users get the impression that the bot is failing in responding correctly the questions and is not dependable enough to be brought into live environment.
