According to documentation, the etc/view.xml is optional when inheriting from a parent theme.
I am inhereting from Magento/blank, so I did not create this file. It gave me this error in developer mode, in default mode the products just won't be displayed.
When I copy and paste the etc/view.xml file from the parent theme, the error is gone and everything works as expected.
