I’m creating a new Gradio space with the sample app.py, but immediately got the “Connection errored out” error after build. Below are the sample app.py that I’m running on the space and the error message (sorry for the long error message). The same error appeared on another of my Gradio space that only got this issue after it was rebuilt. Am I missing something? Thanks a bunch!
app.py:
import gradio as gr
def greet(name):
return "Hello " + name + “!!”
demo = gr.Interface(fn=greet, inputs=“text”, outputs=“text”)
demo.launch()
Error:
Running on local URL: http://0.0.0.0:7860
To create a public link, set share=True in launch().

If you got this error by calling handler() within __get_pydantic_core_schema__ then you likely need to call handler.generate_schema(<some type>) since we do not call __get_pydantic_core_schema__ on <some type> otherwise to avoid infinite recursion.
