Rightly or wrongly, I think the script plugin expects/requires a
BasicAttribute to be produced as output, even if it has no values itself.
I think that's the null it's talking about.

Yes, it's a null pointer in the Java coming out of the script.

We don't in general handle null values in attributes at all. SAML
technically can, but it's really just not done. If you have no value, you
don't send it, we don't encourage the idea of distinguishing between "no
values" and "a value of nil".
