BUG : run the code of "rag.insert...", Matrix content is lost.

[KevinZhuoGpt]

when I ran the program of "rag.insert()..." , I found my llm was offline.
so I stoped my program.
After I started my llm, went on to run the program, my program had error as: json.decoder.JSONDecodeError: Expecting value: line 1 column

I checked vdb_relationships.json.
"matrix": the content had lost.
