┃ I do not have access to the content of any files. I can only provide information I find in the knowledge base. Is there anything else I can help you with? | from the model

It looks like your agent isn't accessing the PDF content properly. Here are a few things you can check:

Is the PDF being read correctly?
Try printing documents after reading the file to see if it contains any data.

Is the vector database storing the content?
    If recreate=False, make sure the data was already indexed.
    Try setting recreate=True when loading the knowledge base.

Is your API key working?
    Print os.getenv("GOOGLE_API_KEY") to ensure it's not None.

Is the Gemini model using the vector database?
    It might not be retrieving the stored content properly.
    Try querying PgVector2 manually to see if the data is there.
