Chroma database error: Index not found, please create an instance before querying

[testdami555]

I am trying different databases with this plugin. I have used Chroma on other projects and it has worked fine. I have tried different configurations to achieve persistence with Chroma and I always get the same issue. The first time always works fine. When I stop the thread. And restart the thread I see the following error when performing a query: "Index not found, please create an instance before querying" 500 Internal Server Error

I have tried with embedding_function=None and embedding_function="text-embedding-ada-002"

The result is the same.

The folder is created and sub folder index (with .pkl and .bin files) The .parquet files have not been created (I have chroma_db_impl="duckdb+parquet") That's ok?

Thanks
