[Bug]: copilot_prompt_invalid: Model gpt-4o-mini-audio-preview does not support structured output

[LastSkywalkerER]

What happened?

I don't quite understand what gpt-4o-mini-audio-preview is and where it could have come from when I try to transcribe audio.

Even inside the container, there is no mention of this model in the ./dist/main.js file.

Anything else?

Here is the config from admin

{"scenarios":{"chat":"gpt-5-mini","image":"gpt-image-1","coding":"gpt-5.1-codex","rerank":"gpt-4.1","embedding":"text-embedding-3-small","audio_transcribing":"gemini-2.0-flash","polish_and_summarize":"gpt-5-mini","quick_decision_making":"gpt-5-mini","quick_text_generation":"gpt-4o-mini","complex_text_generation":"gpt-5-mini"},"override_enabled":true}

Currently the transcript feature only supports the Gemini 2.5 and Gemini 3 series models, please check whether you have a key to configure gemini.

I changed the model in the config

{"scenarios":{"chat":"gpt-5-mini","image":"gpt-image-1","coding":"gpt-5.1-codex","rerank":"gpt-4.1","embedding":"text-embedding-3-small","audio_transcribing":"gemini-2.5-flash-lite","polish_and_summarize":"gpt-5-mini","quick_decision_making":"gpt-5-mini","quick_text_generation":"gpt-4o-mini","complex_text_generation":"gpt-5-mini"},"override_enabled":true}

and I have the gemini key set

but the transcription error has not changed
