Describe the issue

I'm setting up a Python application using the Starter Kit. It worked fine after do the steps from this issue https://github.com/kinde-starter-kits/python-starter-kit/issues/15.

But the "Helper functions" button redirects to a Internal Server Error page. The log printed in my terminal is the following.

I tried to add a "theme" feature flag in my application using the Kinde UI in [My Application] > Releases > Feature flags to check if the issue was fixed, but the flag is not added. The spin icon close to Cancel button runs forever.
