Lab 1.4: Determine the Value Type, Part 3

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?

Anyway, thanks again and all the best.

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).

Hi @Diego_Losey,

You were supposed to use video.movies collection and not the aggregation.movies collection.

That being said, we have released a brand new version of this course which has better and updated content.
