I got errors on fine-tuning due to invalid dataset. Could you help me?

I am working on fine-tuning a model, but it complains. Could you check what is wrong in the following dataset?

NOTE: I have more than 10 examples and no empty space in the jsonl file.

Dataset as .jsonl

{“message”: [{“role”: “system”, “content”: “…”}, {“role”: “assistant”, “content”: " …“}, {“role”: “assistant”, “content”: " …”}, {“role”: “user”, “content”: “…”}]}

{“message”: [{“role”: “system”, “content”: “…”}, {“role”: “assistant”, “content”: “…”}, {“role”: “user”, “content”: “…”}]}
