Describe the Bug

When starting a task to transcribe audio, I see a 404 error on the /audio/transcription/ endpoint in LocalAI (version 3.6.0, but this was also true for older versions)

Client error ip=10.0.0.237 latency="695.836µs" method=POST status=404 url=/audio/transcriptions

and the task fails.

Expected Behavior

The task doesn't fail.

The correct endpoint is /v1/audio/transcription/ and if a reverse proxy is put in the middle with the proper rewrite rule, everything works fine.

Not sure if this is a change in the LocalAI API specification or something else, so basically not sure this is a bug.

To Reproduce

Just run a transcription task with the Nextcloud and LocalAI versions mentioned above.

        "url": "https:\/\/local-ai.myname.cloud"

hello, try adding /v1 to the service url in the admin UI
the models endpoint may have worked without it but the correct url for local ai contains the trailing v1 usually.

[pmarini-nc]

Hello @kyteinsky ,

Yes, that solves the problem and, yes, other tasks depending on other models were working even without /v1.

This is probably documented somewhere in the OpenAI API documentation, the LocalAI being compliant of it.

Thanks for your help!
