Use .count instead of .Length to get length of $taskArgs

if ($taskArgs.Length -eq 0) {

Ever seen this message:

     | The property 'Length' cannot be found on this object. Verify that the property exists.

So, I did some digging, and... while $taskArgs really does seem to be an IList<object>, powershell seems to be totally weird about it and (probably) wraps collections internally or something.

According to https://learn.microsoft.com/en-us/powershell/scripting/learn/deep-dives/everything-about-arrays?view=powershell-7.3#count, you can actually just use the .count property to get the length (tested on my machine). Note the lowercase. That's intentional.

damn... that doesn't seem to work in every case either...

In the case of tasks with no parameters, $taskArgs -eq $null is true... (check for that instead of the count?)
