Flow subflow - trying to test an input type of Array.String

[GoBucks]

I have created a simple subflow with an input type of array.string:

Is this type not an array of strings?  Perhaps I'm misunderstanding it or forgetting something obvious. I then have a For each logic action so I can loop through this array of strings:

And within the loop I'm simply attempting to print to the log:

When I go to test I enter a test value for just one array element:

When I look at the runtime value it appears to be null as if I never provided a value for this array element.

How can I test the input type of Array.String?

define an output....

Well I don't necessarily need an output.  I went ahead and defined one although I'm not setting the output in my example I shared.  What I am unable to do is print the value of this input type (what I think is an array of strings) to the log.  The test doesn't even show that I provided a value at runtime, and I did.  I feel there's something fundamental I'm missing here...

While I see null in my original example, the past few tests I see:

{
    "my_text": {
        "my_text_child0": [
            ""
        ]
    }
}

Again, I provided a value prior to running the test.

Hi,

Your flow looks good. I just tested the same on my side as well and it works. I would suggest deleting the existing input variable and recreating it that might solve this problem. I observe this many times recreation fix these types of issues in flow designer.

Hope that helps!

I executed cache.do and then completely recreated a separate Subflow to test. I once again gave one array element a value and ran the test.  Once again got an empty string even though I entered a value prior to running test:

So then I repeated this on a PDI and same result.  Am I do anything wrong with how I'm entering the test value?  Here's the latest test:
