What is the best way to have an external node script that

Yes. I am almost sure that works. If not, it's a bug.
Maybe it's caching something.
I think the external node classifier is not re-run if the
facts have not changed. There's a feature request to make
it run every time.
However, it would be nice to have the client error out in such
a way that I know there was a problem with the external node
script loading it's info. Anyone?
Something else I have done, and that might suit you, is let the
node classifier script return an almost-empty non-error result,
like this:
---
parameters:
error_message: "Something is wrong"
classes: []
Then the top-level site.pp can do something like this:
if $error_message {
fail("External node classifier says: $error_message")
}
