I'm using Openlayers + GeoServer to draw a new point and save it. But there are some errors.

Code as follows:

function onSaveNewPoint() {

      for(var i = 0 ; i < drawedFeaturePointArray.length ; i++){

      var geometry = drawedFeaturePointArray[i].getGeometry().clone();
      geometry.applyTransform(function(flatCoordinates, flatCoordinates2, stride) {
        for (var j = 0; j < flatCoordinates.length; j += stride) {
          var y = flatCoordinates[j];
          var x = flatCoordinates[j + 1];
          flatCoordinates[j] = x;
          flatCoordinates[j + 1] = y;
        }
      });
      var newFeature = new ol.Feature();
      newFeature.setId('cities.2406.new.' + newPointId);
      newFeature.setGeometryName('the_geom');
      newFeature.set('CITY_NAME', newFeature.getId());
      newFeature.set('GMI_ADMIN', newFeature.getId());
      newFeature.set('ADMIN_NAME', 0);
      newFeature.set('FIPS_CNTRY', '');
      newFeature.set('CNTRY_NAME', '');
      newFeature.set('STATUS', 'test');
      newFeature.set('POP_RANK', 0);
      newFeature.set('POP_CLASS', '');
      newFeature.set('PORT_ID', 0);
      newFeature.set('LABEL_FLAG', 0);
      newFeature.setGeometry(new ol.geom.Point([geometry.getCoordinates()]));

      addWfsPoint([newFeature]);
      newPointId = newPointId + 1;
      setTimeout(function(){
        console.log('next Feature');
      },3000);
    }      
  }

function addWfsPoint(features) {
      var WFSTSerializer = new ol.format.WFS();
      var featObject = WFSTSerializer.writeTransaction(features,
        null, null, {
          featureType: 'WorldCities',
          featureNS: 'http://geoserver.org/WorldCities',
          srsName: 'EPSG:4326'
        });
      var serializer = new XMLSerializer();
      var featString = serializer.serializeToString(featObject).replace('undefined','');;

      var request = new XMLHttpRequest();
      request.open('POST', 'http://localhost:8080/geoserver/wfs?service=wfs');
      request.setRequestHeader('Content-Type', 'text/xml');
      request.send(featString);
    }



Errors as follows:

I've searched online, but still don't know how to resolve this problem. I hope someone here can help me out.

    Please add the XML being posted by the browser in the description, not everybody is a client developer here. – Andrea Aime Sep 17 '18 at 8:29

    @AndreaAime hello AndreaAime,thanks for comment.I've edited the question and added the XML. :) – jerry Sep 17 '18 at 8:37
  • hi. good first question IMO; I reworked the title; removed the error qualifier and gave it a more appealing wording (albeit duplicating the tags....). if you think that is unfitting, you can always roll-back or rework it again. – geozelot Sep 17 '18 at 9:19

The request is lacking all namespaces besides the WFS one, you'll need to add namespace and prefix for the WorldCities feature and attributes, as well as the GML namespaces for the GML elements in it. Use a GeoServer WFS 1.1 response as guidance.
