Start in rag_experiment_accelerator/ingest_data/acs_ingest.py at generate_qna around line 128 and reproduce the 02_qa_generation step. Inspect the generated response shown in the issue and the JSON-loading path; done means the generated Q&A response is handled successfully instead of raising JSONDecodeError.
