[400] Invalid file format. Supported formats: [‘flac’, ‘m4a’, ‘mp3’, ‘mp4’, ‘mpeg’, ‘mpga’, ‘oga’, ‘ogg’, ‘wav’, ‘webm’]

Hello I’m facing an issue for a few days I’m trying to create an automation to transcribe audio files to text (using whisper)
and here’s the message I’m getting all the time : [400] Invalid file format. Supported formats: [‘flac’, ‘m4a’, ‘mp3’, ‘mp4’, ‘mpeg’, ‘mpga’, ‘oga’, ‘ogg’, ‘wav’, ‘webm’]

but my file is in the right format so I don’t really know what to do I even changed my file format from M4a to MP3 or WAV but nothing is working

Any help would be greatly appreciated

You’ll need to first use the Google Drive “Download a file” module to download the audio file to be able to map it correctly in the OpenAI module.

Thank you very much it’s working

It is still not working for me, the difference in my scenario is that I’m using OneDrive with the download step

Also tried with GDrive, same error, any clue?


Welcome to the Make community!

What is the file format, and how are you mapping the file in the OpenAI fields?


Please share screenshots of the module fields and filters in question. It would really help other community members to see what you’re looking at.


Please export the scenario blueprint file to allow others to replicate the issue. At the bottom of the scenario editor, you can click on the three dots to find the Export Blueprint menu item.


Uploading it here will look like this:

Please provide the input/output bundles of the modules by running the scenario, then clicking the bubble on the top-right of each module, taking screenshots of, and copying the contents into this discussion thread:
