     const url =
       serviceUrl +
       layer +
    '/query/?f=json&where=1=1&geometryType=esriGeometryEnvelope&returnGeometry=true&spatialRel=esriSpatialRelIntersects'
     '&inSR=4525&outFields=*&outSR=4525';
    const url = serviceUrl + layer + '/query';
    var params = {
      "f": "json",
      //"where": "OBJECTID='10718'",
      "where": "1=1",
      "returnGeometry": "true",

           const features = esrijsonFormat.readFeatures(data);
           if (features.length > 0) {
             vectorSource.addFeatures(features);
           }
