The notebook for L5 of the Bedrock LLM App course deploys the transcribe lambd, sets the triggers, and the mp3 is loaded just fine. A transcription is generated but a results.txt is never generated. Tried multiple times and even tried manually deploying the pre_lambda_function.py in the notebook (output said it was already loaded), but still could not get a results.txt to be generated. Please advise on how to fix.
