RAG using Azure OpenAI

KNIME Analytics Platform
1

Hello Everyone!

I am new to the Knime Platform, planning to implement RAG using Azure OpenAI as shown in (2.5 - Retrieval Augmented Generation ChatApp – KNIME Community Hub).

Instead of wikipedia articles, I am working on Pdf documents using pdf parser. I have followed all the steps including RAG chatApp configuration but I didn’t get the expected output from the Chat Model Prompter. Below are the some of the warnings.

WARN  Rule-based Row Filter 4:1774:0:1779:1778:1745 Node created an empty data table.

I would check the steps e.g. does the Model return sth when you prompt at all?
Vectorestoreretriever to check whether FAISS has stored sth.
