Elk plugin doesn't work with file from OpenMapTiles.org

Hi,
I’ve tried exporting an OSM file from OpenStreetMaps, but the area is too large so I always get an error.

I went to https://openmaptiles.org/ and downloaded a 33MB file that is “OSM tiles” according to what they say.
I’m trying to use it with Elk, but it doesn’t read the file.
The file type (in the file properties) is “OSM”, so I don’t know what the problem is…

Attached is the error I get in Elk in GH.

error1_elk

Any ideas…?
Thanks
