400 Client Error: Bad Request for url

I get the following error when I try to use the inference API:

requests.exceptions.HTTPError: 400 Client Error: Bad Request for url: https://api-inference.huggingface.co/models/MIT/ast-finetuned-audioset-10-10-0.4593

This url is directly taken from https://huggingface.co/MIT/ast-finetuned-audioset-10-10-0.4593 so I dont know what is wrong.

I tested it with a 1 second long .wav file read into bytes. Seems it isnt working though.
