Vertex AI Conversation Dialogflow CX data store custom summarization prompt

Hi, I am trying to change the custom summarization prompt in the agent settings in Dialogflow CX (Auto Generated Vertex AI conversation). I want it to be fetching the context from data store but the model hallucinates the responses from out source knowledge. In the documentation it only mentioned about the $request.knowledge.answers[0]. Is there some placeholder for data store that I am missing.

Is this is a correct approach?

Hi,

Unfortuntately that is not a correct approach. You cannot access $request.knowledge.answers[0] from that prompt.

Best,

Xavi

Thank you for the reply. Would you mind suggesting some parameters in the prompt so that it fetches answers exclusively from the data store index and not from the LLM’s knowledge?
I appreciate your assistance.
