[Issue] [Kendra-Foundational-LLM-Chatbot] [ No Writes to DynamoDB - No Conversastional Memory ] 

Faced issues with no writes on DynamoDB leading to no memory for the conversation? Wondering if the _guru-kendra-chatbot-chatHandlerLambdaFn_ function should be writing to DynamoDB ? I have tried modifying it but not getting the table schema right.
I noticed that LangChain was removed 8 months ago which might have resulted in no-conversational memory.
