Fix ChromaValueError

✅ Solution

ChromaValueError usually arises when attempting an operation with a collection that doesn't exist or isn't properly initialized, often after a database reset or migration. Ensure the collection exists by either recreating it with `chroma_client.create_collection()` or verifying its presence with `chroma_client.get_collection()` before attempting any operations like adding or querying. If using persistent storage, double-check the persistence directory and ensure the chroma service is running and configured correctly.
