Welcome to the Make community!
You can use the built-in function remove
e.g.:
{{ length(remove(1.array; null; undefined; emptystring)) }}
For more information, see the function documentation in the Help Center and do the tutorials in the Make Academy.
Alternatively, you can also add a FILTER before the Array Aggregator module to prevent empty URLs from reaching the aggregator.
Here are some useful links and guides you can use to learn more on how to use the Make platform, apps, and app modules. I found these useful when I was learning Make, and hope they might benefit you too —
