## Workarounds

1. **** (90% success)
   ```
   try:
    await request.json()
except ClientDisconnect:
    return JSONResponse(status_code=499, content={'detail': 'Client disconnected'})
   ```
2. **** (85% success)
   ```
   async for chunk in request.stream():
    if await request.is_disconnected():
        break
   ```
