[Python] Gradio "AttributeError: 'Image' object has no attribute 'proxy_url'"

Since the Gradio Discord server is busy or does not allow new requests, I'm posting this here. I intend to display an image in the rows of a Gradio Dataset. The error is "AttributeError: 'Image' object has no attribute 'proxy_url'" and seems deep in the implementation of Gradio, so the AI did not help to understand the context.

python -c "import gradio as gr; import sys; print(f'Python {sys.version.split()[0]}\\nGradio {gr.__version__}')"

Python 3.11.11
Gradio 5.23.3


This is the error stack:

Here is the code to reproduce

import gradio as gr
from PIL import Image

white_image = Image.new("RGBA", (16, 16), color=(0, 0, 0, 0))
red_image = Image.new("RGBA", (16, 16), color=(255, 0, 0, 255))

philosophy_quotes = [
[white_image, "I think therefore I am."],
[white_image, "The unexamined life is not worth living."]
]

startup_quotes = [
[red_image, "Ideas are easy. Implementation is hard"],
[red_image, "Make mistakes faster."]
]

def show_startup_quotes():
return gr.Dataset(
samples=startup_quotes,
components=[
gr.Image(type="pil"),
gr.Text()
])

with gr.Blocks() as demo:
textbox = gr.Textbox()
image = gr.Image(visible=False,type="pil")
dataset = gr.Dataset(components=[textbox, image], samples=philosophy_quotes)
button = gr.Button()

button.click(show_startup_quotes, None, dataset)

demo.launch()


Any hints?
