Unrecognized feature on dev tools on my Custom Component

Hi everyone,

I tried making my own custom components in a single package. following this repo: GitHub - dani-37/streamlit_custom_components: Easier way to make multiple streamlit components.

when i run and test the app, i’d always see these errors that is nowhere to be found in my app. wondering if there is a workaround to remove/fix this as well as the deprecated warnings when i try to npm install? thanks!
