You aren't returning the correct number of documents

Atlas Cluster0-shard-0 [primary] aggregations> 

this means your query works but is not as intended by the question. please check the keywords, especially "and"s and "or"s

Same Error !!

can some one please assist and identify anything wrong in the below Query. I get back 877 documents

var pipeline = [{"$match" : {"$and" : [{“imdb.rating” : {"$gte" : 7}},{“genres” : {"$nin" : [“Horror”,“Crime”]}},{"$or" : [{“rated” : “PG”}, {“rated” : “G”}]},{“languages” : {"$in" : [“English”,“Japanese”]}}]}}]

does not meet the requirement

languages contains “English” and “Japanese”

And if I may add to

Your query produce 20 documents as seen in:

and the lab specifies 23 documents:

As a hint, your aggregation should return 23 documents. You can verify this by typing db.movies.aggregate(pipeline).itcount()

Do not try to validate until your pipeline produces 23 documents.
