Guidance on transcription audio with Nova-3 and Whisper model

[DanyMichiels]

Hi,

I'm using Deepgram's SDK to transcribe an audio file.
Nova-3 for diariation and whisper for transcription.
I have implemented it with the callback functionnality.
I'm getting empty transcription results (0 channels, 0 duration) when using transcribeFileCallback with nova-3 and whisper model.
Buffer is 15.61MB, mimetype is audio/mpeg.
Direct transcribeFile works fine with the same buffer. Using @deepgram/sdk v3.13 on Vercel.

Nova-3
model: 'nova-3',
language: 'en',
punctuate: true,
diarize: true,
utterances: true,
utt_split: 0.8,
paragraphs: true,
smart_format: true

Request id: b19df94e-0dab-438c-82a2-56a4bd04c561

Whisper
model: 'whisper',
language: 'en',
punctuate: true,
diarize: false,
paragraphs: true,
smart_format: true

I'm using STT with pre-recorded audio file.

The problem has been solved. It was related to the buffer that had been specified as an object.
