How to read a WFS published through QGIS server with Leaflet

Question

I would like to read a WFS published using QGIS server, with the plugin Leaflet-WFST but an error occurs when the plugin is trying to read the geometry.

Error :

uncaught exception: unknown child element Point

Result of the WFS POST request:

Additional information:

Points came from a PostGIS database (postgresql 9.5 postgis 2.2) then publish using QGIS 2.18.16

The WFS can be read perfectly using a remote computer and QGis desktop

The GetCapabilities of the service: http://54.38.33.23/cgi-bin/qgis_mapserv.fcgi?SERVICE=WFS&version=1.0.0&REQUEST=GetCapabilities&MAP=/home/sebastien/odkResult/indTrees.qgs

Leaflet code:

var layer2=new L.WFS({
                url: 'http://54.38.33.23/cgi-bin/qgis_mapserv.fcgi?MAP=/home/sebastien/odkResult/mangroveTrees.qgs',
                //typeNS:"",
                geometryField:'geometry',
                typeName: 'ind_trees',
                crs: L.CRS.EPSG4326,
                style: {
                  color: 'red',
                  weight: 3
                }
            }).addTo(mymap)
