how to write a wfs- transaction insert with geoserver/postgrsql - postgresql

Question

I have a database and a server tomcat / geoserver and I try to exchange data from openlayers.
So i am trying to write a wfs transaction without success. I do not know what's wrong, geometry?
I tried to copy the example provided in the demonstration without further success:
<ows:ExceptionReport version="1.0.0" xsi:schemaLocation="http://www.opengis.net/ows http://ip_address:8080/geoserver/schemas/ows/1.0.0/owsExceptionReport.xsd"><ows:Exception exceptionCode="InvalidParameterValue"><ows:ExceptionText>Error performing insert: Error inserting features</ows:ExceptionText></ows:Exception></ows:ExceptionReport>
my try :

The srs is EPSG:2154
the openlayers transaction that does not work either :
var wfst = new ol.format.WFS({
featureNS: "http://www.opengeospatial.net/cite",
featureType: "cite:administration"
});
var options = {
srsName: "EPSG:2154",
featureNS: "http://www.opengeospatial.net/cite",
featurePrefix:'cite',
featureType: "cite:administration",
gmlOptions:{featureNS: "http://www.opengeospatial.net/cite",featureType: "cite:administration",srsName: "EPSG:2154"}
};
var node = wfst.writeTransaction(features2154,null,null,options);
console.log('node',node);
var s = new XMLSerializer();
var str = s.serializeToString(node);
result str =

Answer 1

my response :
it lacked the necessary attributes for transaction (not null values in POSTGIS exception)
