Bắt đầu bằng cách tái hiện việc tải PDF lên thông qua endpoint POST /documents và theo dõi các log ingestion của chain-server, đặc biệt là quá trình trích xuất PDF của unstructured và tài nguyên punkt_tab bị thiếu của NLTK. done phải có nghĩa là PDF được nêu trong báo cáo có thể được ingestion mà không gặp lỗi tài nguyên hoặc lỗi tải lên gây hiểu nhầm.
