Document doesn't exist in Movies collections

It looks like in homework chapter, movies collections mentioned but document Languages doesn’t exist in movies collection.So results might vary.
Also, $match Homework looks quite difficult than aggregation $match topic covered in lecture.

Did you meant languages field?
What connect string you used

“type” : “movie”,
“languages” : [
“English”
],
“directors” : [
