Encountered Type Error When Running $gradio cc dev

[koi953215]

I am working on developing my own Gradio package using the code from this repository as a template. I have followed these steps:

1. Cloned the repository.
2. Navigated to the frontend directory and ran npm install.
3. Modified app.py to import ImageSlider from the backend directory instead of using the pip install

However, when attempting to test locally using the command "gradio cc dev", I encounter the following error:

Could you please provide instructions or troubleshooting steps to address this error? Any additional information or guidance on setting up the local development environment correctly would be highly appreciated.

Thank you for your help!
