Dify version

1.1.3

Cloud or Self Hosted

Self Hosted (Docker)

Steps to reproduce

I have used the hjlarry/audio plugin to convert the responses generated by the LLM into audio output. However, after running the workflow, I encountered the following error: Run failed: plugin daemon: {"message":"Key: 'InvokePluginRequest[github.com/langgenius/dify-plugin-daemon/pkg/entities/requests.RequestInvokeTTS].Data.InvokeTTSSchema.Voice' Error:Field validation for 'Voice' failed on the 'required' tag","error_type":"PluginDaemonBadRequestError","args":null}, code: -400. The text-to-speech model deployed is Voice of CosyVoice2-0.5B (langgenius/xinference/xinference). In the Dify interface, under the Text To Speech node, the select a voice dropdown menu is not clickable and there is no list of voices available. CosyVoice2-0.5B is running via Docker deployment of Xinference. How can I resolve this issue?

Hello @simplify123! I'm Dosu, your friendly bot here to help you with bugs, questions, and becoming a contributor while you wait for a human maintainer. Let's tackle that TTS issue together! 🚀

There is a similar closed issue that might help you resolve the problem. The solution suggested was to ensure that the voice parameter is correctly handled and passed through the relevant functions and API calls. You may need to modify the code to include the voice parameter where necessary, such as updating the XinferenceModelExtraParameter class and related methods to include and handle the voice parameter. Additionally, ensure that your Dify Docker deployment is correctly configured to access the Xinference endpoint by using the machine's IP address instead of localhost [1].
