OpenAI-API-compatible plugin can't add self hosted STT model

[tyh-carl]

I hosted a STT model mlx-community
/
Qwen3-ASR-0.6B-bf16 on my Mac Studio.

And try to add it to dify via openai-api-compatible plugin.

However, when I press add, the api server shows "ValueError: Unable to detect audio format from bytes" and dify shows Internal Server Error message.
