Hi @thorsten-wack ,
In earlier versions, there were no strict checks of whether Action catalog mentioned in ‘create task’ exists or not. It used to still go ahead and create Actions without Action catalog linking. However with 22.4, Action catalog linking has been made strict
If you remove leave Action catalog empty, it will not throw an error. However if you mention an Action catalog and catalog does not exist in the folder where Action is being created, it will not proceed with Action creation.
