execute system task

Hi,

I am trying to make use of the new system task in a system flow. However, it seems to do nothing at all within my system flow.

Release notes 2021.3 :

**Execute system task** - allows using tasks inside system flows. Note that the default procedure will not be executed when using this process action. Any task parameters that are not set as input and output will not be used by Indicium to run the task. A validation is created for this.

I am not using a def and no variables. I am simply trying to make a change in the database using a control procedure. I am using a dummy task to make the flow available in the menu.

Why does the code not run?
