Error upgrading to Hopsworks 3.0 on Premises

Upgrading a Hopsworks 2.5 feature store to Hopsworks 3.0 with

./bin/karamel -launch hopsworks-upgrade-3.yml

I got an error

se.kth.karamel.webservice.KaramelServiceApplication: 
Inalid yaml file; Invalid attributes, 
all used attributes must be defined in metadata.rb files

Any hints are really appreciated.

What I did
I copied the generated cluster-defns/hopsworks-installation.yml file to the haramel-0.6/hopsworks-upgrade-3.yml,
changed the attribute
cookbooks/hopsworks/branch to 3.0
and added the attribute attrs/install/current_version: 2.5

The Karamel console Output is:
