RE: Options for YAJLINTO to handle a null array

Thank you!

I've tried various iterations of using the countprefix option. I was just surprised to see the count of the errors array at "1" when it's received as "null". In this case, I supposed "errors" is present, but the underlying "field" and "messages" are not?

I'm considering creating separate DS for each situation and placing them in nested monitor statements... Or is that "bad form"?
I would expect to receive a "successful" post of the shipment most of the time.

Hello Greg

We ran into this a while ago and experimented with null indicators and so on but that won't work.
You can use the countprefix keyword instead to handle this. It will be zero with an empty or null array.
