Describe the issue

I encountered an issue during the final stage of the GraphRAG indexing pipeline where the create_final_community_reports step failed, but the knowledge graph was successfully created. The error appears to be related to an unsupported response_format with the OpenAI model.

Steps to reproduce

1. Installed GraphRAG via pip install graphrag.
2. Ran the indexing pipeline using the following command: python -m graphrag.index --root .
3. The pipeline progressed successfully through stages like:

• create_base_text_units
• create_base_extracted_entities
• create_summarized_entities
• create_final_entities
• create_final_nodes
• create_final_relationships
• create_final_communities

4. It failed at the create_final_community_reports step.

Are you still seeing this error? "json_object" is definitely supported so this seems like it was either a temporary glitch, or there is something else going on. Can you upload your indexing-engine.log?

Thank you for your response. But yes, I’m still facing the same issue with the "json_object" error. I've attached the indexing-engine.log file and the logs.json files. indexing-engine.log logs.json
