The error you're encountering with the Tongyi QwQ-32B model in Dify seems to be related to the
incremental_outputparameter. The model only supports this parameter being set to a specific value, which might be causing theServiceUnavailableErrorwith a 400 status code due to an invalid parameter setting.To resolve this issue, ensure that the
incremental_outputparameter is correctly configured according to the model's requirements. Unfortunately, specific details about the required settings forincremental_outputin the Tongyi QwQ-32B model are not available in the current documentation or codebase [1]. You might need to check any available documentation or configuration guides specific to the Tongyi QwQ-32B model for the correct parameter settings.Additionally, if the error persists, consider reviewing the integration of knowledge bases or tools, as they can affect model invocation, especially in agent mode [2].

For bugs related to plugins, you need to provide the plugin version as well.

I tried 0.0.14, 0.0.15, and 0.0.16 all reported errors, but I remember that the 0.0.14 used before seemed to work fine.
In another v1.0.1 Dify deployment instance, with 0.0.14 version of the Tongyi Qianwen model plug-in, it works fine.
