----------------------
The error message you're encountering indicates that the
search
method is being called on a
NoneType
object. This typically means that the object you're trying to call the method on hasn't been properly initialized.
In the context of your code, it seems like the
self._aclient
object is
None
. This object is likely responsible for handling the search queries in your vector index or database.
Here are a few things you could check:
- Initialization of the query engine: Ensure that the query engine (or the client object) is being correctly initialized. For instance, in the case of LlamaIndex, you might be using a method like
vector_index.as_query_engine()
to initialize your query engine. Make sure vector_index
is not None
and is properly set up.
- Connection to the database: If
self._aclient
is a client object for your database (like Qdrant DB), make sure that the connection to the database is properly established. This could involve checking your connection parameters, ensuring the database server is running, etc.
- Compatibility of the database with ragas and LlamaIndex: Ensure that the database you're using (Qdrant DB) is compatible with both ragas and LlamaIndex. You might need to check the documentation or reach out to the maintainers of these libraries for this information.
Unfortunately, without more specific information about your code and setup, it's difficult to provide a more precise solution. If you continue to encounter issues, I would recommend reaching out to the maintainers of ragas and LlamaIndex for more specific assistance.
