jsonutil list to array question

[iamzip]

So I'm trying to use json in my scripts and I have a question about arrays. I've searched the api and around the web and I can't find a direct answer.  I'm building lists in a json file then later filling papyrus arrays with them. My question is, if the list doesn't exist in json, for whatever reason, what does the listtoarray function return? Do I need to check before passing, ie:

 

Spoiler

If(jsonutil.intlistcount("filename", "listname") > 0)

    Array = intlisttoarray("filename", "listname")

EndIf

 

Or if it doesn't exist and it doesn't pass anything, I'm assuming I'd have to fill the array another way, ie:

 

Spoiler

Array = IntListToArray("filename", "listname")

If(!array)

    Array = createintarray(1, -1)

EndIf

 

Or does it already pass a size 1 array of -1?
