SIL/Power Scripts - update Portfolio target start/end

[Konrad Garus]

I'm trying to update Portfolio target start/end date from Power Scripts. I'm even trying something as simple as:

%k%.customfield_10109 = currentDate();

However, that ends up with the following error. Any other custom date field works, it seems to be something special about Portfolio. Any ideas on how I can get it to work with these fields, or work around it?

The error is:
