Flow Custom Action Output Not Working Correctly

[Casey23]

I created a custom action to use in a flow. Basically what it does is look at a system property containing usernames in a CSV format. (ex. username1,username2,username2) It can be used for other types of system properties in that format, I just happen to be working with one that has usernames. 

Inputs:

Script step:

Code snippet for easy reading:

(function execute(inputs, outputs) {
    var raw = inputs.system_property || '';
    gs.log("CSV Parser - Raw Input: [" + raw + "]", "CSVParser");
    var parts = raw.split(',');
    var cleaned = [];
    
    for (var i = 0; i < parts.length; i++) {
        var val = parts[i].trim();
        if (val) {
            cleaned.push(val);
        }
    }
    gs.log("CSV Parser - Cleaned Array: [" + cleaned.join('|') + "]", "CSVParser");
    outputs.array = cleaned;
})(inputs, outputs);

In the log statement in the script, I can see that I'm getting the proper usernames when the action executes. However, in my flow, something isn't translating. I added a log step and added the output variable "Array" in the message, but it shows up blank.

Log action in my flow:

System log:

What am I missing here? I set this up similar to another custom action I have, granted that one is a string instead of an array.string, but I can't seem to figure out why this isn't working correctly.

TIA

I ended up comparing to another custom action in the system, and it looks like adding that Array pill to the Outputs section of action now shows it in the logs.
