Hi, I have a similer scenario to this Topic: Check if an array contains a value - How To - Make Community

For some reason, the filter is always returning false (does not contains).
Any idea?

The Scenario

Array Aggregator

The Filter
The user_name is Assad. However this does not changes anything, i tried to manually write it, still not work.
