AssemblyAI - Upload audio file action
The Upload audio file action uploads raw audio bytes to AssemblyAI and returns a URL you can use as the audio source when you create a transcript.
SEND RAW BYTES, NOT JSON
Map a file content datapill so the request body is raw audio bytes (application/octet-stream). Sending JSON instead returns a URL that fails when you try to transcribe it.
