Top-level import soundfile in the Transcribe handler breaks /v1/messages streaming without the proxy extra

BerriAI/litellm#45379 · upstream bug reproduced by running the issue's own reproduction

✓ Badgr rejects this response

acreate(stream=True) raised ModuleNotFoundError before any chunk, so the client received an empty stream.

Outcome contract verdict: stream ended without a terminal [DONE] or message_stop event. The attempt is recorded as failed (invalid_outcome) instead of a verified success, so it is not billed as a good answer and can fall back to another route.

What the upstream returned (replayed)

The output the bug produces, taken from the issue’s reproduction and fed to Badgr’s validators. Not a live provider call.
