An error occurred: Extra data: line 21602 column 4 (char 18734083)

When I try to use LightRAG for a local query, I encounter the error: "An error occurred: Extra data: line 21602 column 4 (char 18734083)".

This seems to be an issue with the JSON format. Did it occur during the query process? Do you have the full logs and code snippet available for debugging?

I just input a string, and set the prompt as follows:
f'''
xxx
{string}
xxx
'''

However, the string itself is quite complex and may contain some escape characters.
It seems that no other errors were reported, and no log file was generated.

I found this error occurred during initialization:

        embedding_dimension =  await get_embedding_dim()
        #print(f"Detected embedding dimension: {embedding_dimension}")

        rag = LightRAG(
            working_dir=WORKING_DIR,
            llm_model_func=llm_model_func,
            embedding_func=EmbeddingFunc(
                embedding_dim=embedding_dimension, max_token_size=8192, func=embedding_func
            ),
        )

I tried changing the WORKING_DIR, and the error no longer occurs.

I realized that I should have input JSON data the first time, which might have caused an issue with the cache. After that, inputting strings didn't work either.
