Hi,
This error occurs when viewpoints referenced in your model are not installed on your current platform.
It points at filtering, which was installed on your 5.2 but not on your 6.1.
You can find it here Release v1.6.1 · eclipse/capella-filtering · GitHub

I was successful with your suggestion. Thank you very much.
diagramstyler comes with the PVMT add-on.
