Failed to Transcribe audio chunk

[coding-with-umar]

Hi, I’m working on transcribing a live YouTube video. I’m fetching the audio from the live stream and passing it into Faster Whisper. The issue I’m encountering is that after a while, or sometimes even right from the start, it fails to transcribe certain audio chunks, leading to gaps in the transcription. Could you provide some insight into what might be causing this and how I can resolve it?

Here’s the error I’m seeing on the server side:
INFO:faster_whisper:Processing audio with duration 00:04.492
INFO:faster_whisper:Processing audio with duration 00:14.476
ERROR:root:[ERROR]: Failed to transcribe audio chunk: cannot access local variable 'last_segment' where it is not associated with a value

Note: I’ve tried every model size, and I’m working with Urdu language transcription.
