facebook/MusicGen · API text only not working

Hello, I keep trying the third example of the API documentation exactly as it's written, and getting an error. The other examples work fine.
Here is the code I'm running:


client = Client("https://facebook-musicgen.hf.space/")
result = client.predict(
                "Howdy!",	# str  in 'parameter_15' Dataset component
                fn_index=2
)
print(result)

And here's the error:

  File "/Users/cameronglass/opt/anaconda3/lib/python3.9/site-packages/gradio_client/client.py", line 836, in _predict
    output = result["data"]
KeyError: 'data'

During handling of the above exception, another exception occurred:

    if "error" in result and "429" in result["error"] and is_public_space:

Any ideas? Thank you
