When input WAV file is silent, it still throws an error

[binarykitchen]

When the recorded WAV file is silent, no sound, this error is still being thrown: Operation failed: Transcription failed or produced no output

Full error details are:

    err: {
      "type": "Error",
      "message": "Operation failed: Transcription failed or produced no output.",
      "stack":
          Error: Operation failed: Transcription failed or produced no output.

              at process.processTicksAndRejections (node:internal/process/task_queues:105:5)
    }

When silent, I expect no error to be thrown and just an empty VTT file to be generated with no captions. It's ok to have no output, nothing wrong with that.

Thoughts?

I see you have this code:

		const transcript = await executeCppCommand(command, logger, options.withCuda)

		if (!transcript) {
			throw new Error('Transcription failed or produced no output.')
		}

I would differentiate between transcription error and having no output, both aren't the same.
