Using HF spaces via http request?

If everything didn’t work, I would understand, but it seems that some of it works. It’s a strange behavior.

from gradio_client import Client, handle_file

client = Client("stabilityai/stable-fast-3d")
result = client.predict( # it works.
		image=handle_file('https://raw.githubusercontent.com/gradio-app/gradio/main/test/test_files/bus.png'),
		fr=0.85,
		api_name="/requires_bg_remove"
)
print(result)

result = client.predict( # it fails.
		input_image=handle_file('https://raw.githubusercontent.com/gradio-app/gradio/main/test/test_files/bus.png'),
		foreground_ratio=0.85,
		remesh_option="None",
		vertex_count=-1,
		texture_size=1024,
		api_name="/run_button"
)
print(result)
