Cannot add litteral array with SetUnion

[npen]

Hello,

Using SetOperators.SetUnion:

SetOperators.arrayAsSet("aField").union("anotherField")

How can I reproduce this expression that works fine in Mongo, when one field is a single value and needs to be wrapped in square brackets:

$setUnion: [ "$arrayOfStringField", [ "$stringField" ] ]

Thanks
