Fix issue with memory in learning path chat Chain

[gksoriginals]

Right now answering questions from documents and providing learning path urls are implemented as separate chains. Uploading learning path details to vector store was not working due to some reason. We try to classify user input as learning path query or not and then if learning path query a new chain with context learning path info will answer the question. Otherwise normal Document retrieval chat is initiated.

• Issue here is I am unable to add memory to the learning path chat chain
• Try to fix this by adding learning path query to vector store.
• If not working find fix for adding memory to learning path chat chain
