validateLab1 "A pipeline stage specification object must contain exactly one field."

I open the CMD where the .js file is loaded
load the file (true) works
validate error message = “A pipeline stage specification object must contain exactly one field.”

MongoDB Enterprise Cluster0-shard-0:PRIMARY> var pipeline = < deleted >
MongoDB Enterprise Cluster0-shard-0:PRIMARY> pipeline.itcount()

I also used this query and the same thing happened:

var pipeline = < deleted >

First of all, please follow Forum guidelines and do not post answers, or potential answers or detailed code in the Forum. I have edited your post to remove those references. Thanks.

I believe that you have not defined your pipeline variable correctly. You show pipeline.itcount() to give the correct value 23. But the correct version of the pipeline would be db.movies.aggregate(pipeline).itcount() – If you redefine your pipeline variable correctly, I think you’ll get the correct answer. Good luck.
