Hello,
Current state:
When checking out the CKG project from the master branch and running the CKG App it returns "500 Internal Server Error".
Cause of the error:
This error is caused by the interaction of a new Jinja dependency (the version is not fixed in the requirements.txt) with old flask/dash dependencies. As described in this Issue Flask(1.0.x) and Jinja2(3.1.1) are not compatible.
Related CKG issues:

Implemented bugfix in this pull request:

  • update dash and flask from 1.x.x -> 2.x.x (ensures compatibility with newer Jinja2 versions)
  • simplify dash multi page code by using the new multi page app support
  • set all dependencies in requirements.txt

Thanks in advance!

…y: upgrade flask (1.x -> 2.x) and dash (1.x -> 2.x) and adapt ckg code accordingly (use new dash pages feature and remove boilerplate navigation code)
