Hi, first of all, thanks for putting all the course together, I am enjoying it and it is well explained.
I am still in the beginning but Lab 1.4: Determine the Value Type, Part 3 question says: “What is the value type of the year field for documents in the video.movies collection?”
I know this is going very much into detail but my aggregations.movies collection shows 0.1% strings. Maybe the correct answer for the lab should contain both int32 and strings instead of int32?
The answer is int32 and only int32 (Not string). Look at the schema.
The aggregate returns a cursor to the documents produced (Not string or int32). Anyway aggregate is not part of this course (Hard to know how you get this output).
