Component directory error after uploading component to testpipy

I have developed a new component and uploaded the project to testpypi. I have installed the package in a new environment and now try to import import it. However, I get the following error when I try to import the package: “streamlit.errors.StreamlitAPIException: No such component directory”. The error is related to line 29 in my init.py file where I declare the component.

Can you figure out why I get this error and how to resolve it?

GIT repository: GitHub - sbackp/streamlit_navbar001: streamlit horizontal navbar which can be embedded in columns
