@mamema Hello there! I'm here to assist you with any bugs, questions, or contributions you may have. Let's work together to resolve your issue.

There is a known issue in Dify version 1.0.0 where the system incorrectly requires a rerank model even when rerank is disabled in the knowledge-base settings. This bug has been fixed in a subsequent update (PR #15235). As a temporary workaround for version 1.0.0, you need to configure a rerank model in the Model Provider page by adding a rerank model API key, even if you don't intend to use it ^[1].
