ERROR:example:Failed to ingest document due to exception Unable to get page count.

Beginnen Sie mit den Anweisungen in README und dem Beispiel unter GenerativeAIExamples/RAG/examples/basic_rag/langchain und verfolgen Sie anschließend anhand der gemeldeten Logs den Pfad zur Dokumentaufnahme im chain-server. Prüfen Sie, wie das Beispiel die PDF-Abhängigkeit hinter dem Fehler bei der Seitenanzahl behandelt; abgeschlossen ist die Aufgabe, wenn das Beispiel das hochgeladene PDF ohne eine 500-Antwort aufnehmen kann.
