WMS GetFeatureInfo JSON error

Question

I'm trying to get informations from geoserver with AjaX jQuery of my spatial data at the clicked point using WMS GetFeatureInfo. But I have this ERROR :

http://localhost:8082/geoserver/schemas/wms/1.3.0/exceptions_1_3_0.xsd"> Invalid format 'text/javascript', supported formats are [text/plain, application/vnd.ogc.gml, text/xml, application/vnd.ogc.gml/3.1.1, text/xml; subtype=gml/3.1.1, text/html, application/json]

var clicked_coord;
var onSingleClick = function(evt){
    var coord = evt.coordinate;
    console.log(coord);
    var str = coord;
    var source1 = urldeep;
    var source2 = urlground;
    var layers_list = source1 + ',' + source2;
    var view = map.getView();
    var viewResolution = view.getResolution();
    url = groundwatertable.getSource().getGetFeatureInfoUrl(
        evt.coordinate, viewResolution,view.getProjection(),
        {
            'INFO_FORMAT': 'application/json',
            'FEATURE_COUNT': 20,
            'LAYERS': layers_list,
            'QUERY_LAYERS': layers_list
        });
    console.log(url);
    if (url) { //call parseResponse(data)
        clicked_coord = coord;
        $.ajax(url,
            {dataType: 'jsonp'}
        ).done(function (data) {
            });
    }
