GatherTextFromAssets commandlet never matches anything

Thanks for your answer, Sarge!
Could you please clarify what exactly is wrong with my syntax? I just put single asterisk as a filter - that should be straightforward.
The Dashboard provides plain text input for entering include filter, and if I put asterisk there, it generates exactly the same config as I did, except adding “ShouldGatherFromEditorOnlyData=false” line which doesn’t change much.
