Unable to fit the map to the existing extent

[deviirmr]

I have add a geojson point layer to the map and then I use function
map.fitBounds(pointGeojsonLayer.getBounds());

I noticed pointGeojsonLayer.getBounds() return an extent in epgd:4326 cordinate only which is not get fitted on the polar map.
do I need to project the output of pointGeojsonLayer.getBounds()
