Camunda best-practices Authorization Required

Most recently, I read the “best-practices” manual.
Why now when clicking on the link authorization began to be required?
I get error 401 …

take stage out of the link and it should work

Look at the main menu of the page at
Each menu item in its url contains “stage”. Links are incorrect. Please fix it.

Thanks for the hint - we recently updated the CI/CD process and seem to broke this. We will fix it asap.
