Including the metadata field in the response is crucial for the knowledge retrieval module in the Dify workflow because it provides essential context and identifiers for the retrieved data. Without this metadata, the system may not be able to properly track or utilize the retrieved information, leading to potential errors or inefficiencies in the workflow ^[1].
