I can not import the geojson file on Yandex maps. What is the problem, does anyone know?

Question

Yandex maps

There is a ready-made file, you need to import it to the map, but there is a problem when importing.

The file itself must not be broken, which is the problem I can not understand, perhaps Yandex has its own criteria that are not met.
Here is the code.

run the file for validity - geojsonlint.com
recommend crs to remove and observe the sequence of polygon points .
