Hey @fancywus! I'm here to assist you with any bugs, questions, or contributions you have for Dify. Let's tackle this issue together!

To resolve the 400 Client Error when adding an OpenAI-API-compatible reranker model in Dify version 0.15.3 using Docker, you should upgrade to Dify version 1.0.0 or higher. Additionally, ensure that the OpenAI-API-compatible plugin is version 0.0.6 or higher. The fix for the issue related to the top_n parameter has been implemented in these versions, eliminating the need for manual code modification [1].

Is there any other solution besides upgrading the version? As version 1.0 is a major upgrade, we are currently not considering exaggerating the version upgrade.

I saw you mentioned elsewhere that the reranker.py file could solve the problem. I tried using the default settings but it still didn't work. After I made the modifications, I restarted the Docker service, but it still reported an error.

Hi, @fancywus. I'm Dosu, and I'm helping the dify-official-plugins team manage their backlog and am marking this issue as stale.

Issue Summary:

  • You encountered a 400 Client Error when adding the "bge-reranker-v2-m3" model in Dify v0.15.3 self-hosted via Docker.
  • The error was related to the top_n parameter.
  • The recommended solution was to upgrade to Dify v1.0.0+ and OpenAI plugin v0.0.6+, where this issue is fixed.
  • You were hesitant to upgrade due to the major version change and tried manual modifications without success.
  • The issue remains unresolved without upgrading.

Next Steps:

  • Please let me know if this issue is still relevant with the latest version of the dify-official-plugins repository.
  • If it is, you can keep the discussion open by commenting on this issue; otherwise, I will automatically close it in 5 days.

Thank you for your understanding and contribution!
