hello guys!
i'm facing a problem of mouseover event in leaflet

here is my code :

function highlightFeature(e) {
        var layer = e.target;
        const { name, CWILAYA } = e.target.feature.properties;
        setSelected({
            name: name,
            CWILAYA: CWILAYA

        });
        layer.setStyle({
            weight: 6,// change the weight  of  a state 
            fillOpacity: 1
        });
        if (!L.Browser.ie && !L.Browser.opera && !L.Browser.edge) {
            layer.bringToFront();
        }
    }
function onEachFeature(feature, layer) {
            layer.on({
                mouseover: highlightFeature,// call the function when mouseover  
            });
