Passing data to a Sub Flow Input of Array.String type

[Steven Parker]

So I have a Sub Flow with an input variable of type Array.String and it's named 'pcname'.  If I test the flow and just type a name in there it works fine.  However, when I use the Code Snippet and try to pass a string variable (converted to an array) to that Sub Flow input, it errors out.  

How do I pass data to the 'pcname' "Array.String" input variable on the Sub Flow?  I am just passing 1 variable for now.

As suggested in the script editor when first expanding it, you need to return something, and the 'current.variables' convention used everywhere else in ServiceNow is a foreign concept to Flow Designer.  So in a simplified example when you add a Subflow action and toggle the script, a one line script would be similar to 

return fd_data.trigger.request_item.variables.computer_name;

when you type fd_data. you'll see a prompt for the next available option, then even though 'variables' doesn't prompt, it works.  Once you can get a Catalog Item variable passed into a Subflow string input, you would use the same syntax in your script pushing that variable to an array, etc.  You drag a data pill or write a script for each subflow input individually, so your try block is not needed.
