Lack of x limit and height on UIScrollView at autorun

Disclaimer: I saw an SO method that involves adding a UIView (called contentView) to a UIScrollView and putting all that content. I do not want to use this technique, as I would like to understand why I have a current problem.

I have a UIScrollView by UIView by default, the UIViewController, its UIScrollView has 4 limitations: one on each side (trailing, top, lead, bottom) so that it binds the parent to the UIView. It works!

UIScrollView working limitations

But when I want to add a UIImageView to a UIScrollView, and I want it to be glued to its parent sides (end, top, leader) + specific height, now I have a problem.

Broken UIImageView Constraints

It says:

Scroll View: Has ambiguous scrollable height
Scroll View: Needs constraints for: X position or width
