Is this another gradio version issue?
Yeah. An old Gradio bug. Updating Gradio will probably fix it. If you want to resolve it without updating the current version, try ssr_mode=False on .launch().
ssr_mode=False
.launch()
app.py
# Launch the Gradio interface demo.launch(ssr_mode=False)
pydantic==2.10.6
Thanks! ssr_mode does the trick
