Writing graph with 0 nodes, 0 edges

[ericskh2]

Hi, every time I ran insert() in using_llm_api_as_llm+ollama_embedding.py for a few hours, I received the sentence INFO:nano-graphrag:Writing graph with 0 nodes, 0 edges, then received an error openai.APIConnectionError: Connection error. Could you share suggestions for a possible fix? Thank you very much.
