Chat agent was working but is now unable to answer questions

My chat bot was working properly yesterday and was able to answer all questions. Today, I’ve tested again and now it can’t answer many questions at all and responds “I don’t know”. (I set the chat bot so respond with I don’t know if it doesn’t know the answer to something).

The questions I’m asking are all within the vector database so it should be able to answer and was doing so yesterday. I’m unsure why it is now unable to answer the same Q’s.

The only differences between yesterday and today are:

  1. I upgraded from 1.67.0 (Stable) to 1.68.0 (Beta)
  2. I deleted the original Chat trigger node and replaced it with a new one so that I could make chat publicly available. (The original chat node wasn’t showing the public option).

Note: After I created the new chat trigger node, I retested the Data feed workflow to repopulate the vector databsae.

I’ve attached screenshots of both the data feed and the AI agent workflows.
