Bug Description

What Happened

When creating an agent application, the binding of the Assistant Agent to the knowledge base fails. The error occurs due to the initialization of the RetrieverResource failing, which is caused by the lack of a configured reranker.

Expected Behavior

The initialization of the RetrieverResource should succeed, allowing the agent application to bind to the knowledge base successfully.

Steps to Reproduce

  1. Create an agent application.
  2. Attempt to bind the agent application to a knowledge base without configuring a reranker.

Additional Context

No additional context is provided.

Are You Willing to Submit a PR?

Yes, we are willing to submit a PR to resolve this issue.

Solution

To resolve this issue, we propose the following solution:

  1. Add a configuration option for the reranker in the agent application.
  2. Modify the RetrieverResource initialization to check for the presence of a configured reranker.
  3. If a reranker is not configured, provide a default reranker or throw an error indicating the need for a configured reranker.

By implementing this solution, we can ensure that the agent application can bind to the knowledge base successfully, even in the absence of a configured reranker.

Conclusion
