Vertex AI Conversation app not giving useful answers

[koverholt]

The agent behind the demo app at https://vertex-ai-conversation.web.app/ is not giving useful answers:

The agent in Dialogflow CX is still wired up to a website data store, and utterances are triggering results from Vertex AI Search, for example from the full debug response:

        {

          "status": {
            "code": "OK"
          },
          "responses": [

            },

            },
            {
              "document": "projects/964731510884/locations/global/collections/default_collection/dataStores/google-store-demo-app_1691005340663/branches/0/documents/ba805a92771b34211cae0a59ecedf24a",
              "debugId": "7a2a35ad-a9ec-4717-bb6b-e1811cedb4ba",
              "url": "https://store.google.com/us/product/otterbox_defender_pixel_6_pro",
              "text": "Ucs content search result with 1 answers, 0 passages, 3 segments"
            },

So I'm looking to see if there are any known issues with Vertex AI Conversation or if this issue is specific to this agent.

I'm not sure what happened to the original agent and why it's not returning data store answers. I had an identically configured agent that I was able to switch to in #264, so I did that so that the sample app works for now, and I'll continue to look into why the original agent stopped working.
