Hey @all,
could someone explain the error message in more detail to me? As I see it, it wants to achieve that I provide a Value for every outcome of the computation - however, for example adding another one for the !Filled case has not removed the error.

@joerg-fierce-kelp: Computations within repeatable groups always need a precondition assuring that at least one field is filled for the respective repetition. Could you please try to set “GroupFilled(RuleGroup) and FieldFilled(/root/a)” as Precondition?
This behavior will be improved with <INTERNAL_LINK>
Thank you!
“GroupFilled(RuleGroup) and FieldFilled(/root/a)” is accepted for example in Picus 23.2.0. However, we are using Picus in Version 21.3.8 which does not accept the line as an input there. I will try to find another solution to my underlying modelling problem. Thank you, anyway!
