Node red, home connect alt and a siemens dishwasher

I want the dishwasher to start at a specific time and run a pre-selected program.
For this I am using the “Home Connect Alt” integration.
However, I’m running into a problem: I can’t select a program.
I am using this simpel flow.

I am using an action node

However, this isn’t working; the error message I get is:

Does anyone have a solution, or can someone tell me what I’m doing wrong?

Thanks in advance,
Hans

Thank you.
It works.

Greetings Hans
