Chunks not retrieved from Azure AI Search Knowledge Source

[arnabbiswas1]

Because of the following code retrieval is failing silently. It's not returning any error, but it's not retrieving any chunks as well.

KnowledgeRetrievalLowReasoningEffort should be replaced with KnowledgeRetrievalLowReasoningEffort()

result = retrieval_client.retrieve(
    retrieval_request=KnowledgeBaseRetrievalRequest(
