[zanesq]

Describe the bug

Sending an audio transcription request to eleven labs with a valid api key fails and returns with

POST http://127.0.0.1:51228/audio/transcribe/elevenlabs 412 (Precondition Failed)
(anonymous) @ useWhisper.ts:139

await in (anonymous)
mediaRecorder.onstop @ useWhisper.ts:297
useWhisper.ts:171 Error transcribing audio: Error: Transcription failed
at useWhisper.ts:160:17

To Reproduce
Steps to reproduce the behavior:

1. Go to settings and put in an eleven labs key and choose eleven labs as the provider
2. Click on mic in chat and try to transcribe
3. See error message

Expected behavior
It should work with the eleven labs api and the chat should revert back to chat instead of staying in recording mode if there is an issue.
