      execute script
      { $setUnion: { [ "a", "b", "c" ], [ "b", "a", "a", "d" ] }}
      or

      { $setUnion: [ "a", "b", "c" ], [ "b", "a", "a", "d" ] }
      Show
      execute script { $setUnion: { [ "a", "b", "c" ], [ "b", "a", "a", "d" ] }} or { $setUnion: [ "a", "b", "c" ], [ "b", "a", "a", "d" ] }

      When execute
      { $setUnion: { [ "a", "b", "c" ], [ "b", "a", "a", "d" ] }}
      or

      { $setUnion: [ "a", "b", "c" ], [ "b", "a", "a", "d" ] }

      either returns: "b", "a", "a", "d"

      1. union does not work. expected result for union should include: "c", "b", "a", "d"
      2. duplicated items do not removed from the result.
