WFS GetFeature: NamespaceUri mixup

KevinDyke · ‎12-13-2019

Hi,

I'm attempting to consume features from a hosted WFS service on ArcGIS Online. I'm using the same layer used in the WFS example for the JavaScript API (WFS Layer | ArcGIS API for JavaScript 3.30 ).

The ArcGIS JavaScript example works fine, but fails when I attempt to read the layer using Leaflet-WFST. Looking closer at the response to the GetFeature request, note the value for xmlns:JapanPrefectures2018 in line 5.

<?xml version="1.0" encoding="utf-8" ?>

<wfs:FeatureCollection xmlns:xs="http://www.w3.org/2001/XMLSchema"
 xmlns:wfs="http://www.opengis.net/wfs" xmlns:gml="http://www.opengis.net/gml" 
xmlns:JapanPrefectures2018="http://dservices.arcgis.com/arcgis/services/V6ZHFr6zdgNZuVG0/JapanPrefectures2018/WFSServer"
 xmlns:xlink="http://www.w3.org/1999/xlink" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 timeStamp="2019-12-13T20:54:48Z"
 numberOfFeatures="unknown"
 xsi:schemaLocation="http://www.opengis.net/wfs http://schemas.opengis.net/wfs/1.1.0/wfs.xsd 
http://www.opengis.net/gml 
http://schemas.opengis.net/gml/3.1.1/base/gml.xsd 
http://dservices.arcgis.com/arcgis/services/V6ZHFr6zdgNZuVG0/JapanPrefectures2018/WFSServer 
https://dservices.arcgis.com/V6ZHFr6zdgNZuVG0/arcgis/services/V6ZHFr6zdgNZuVG0/JapanPrefectures2018/MapServer/WFSServer?service=wfs%26version=1.1.0%26request=DescribeFeatureType">‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

The value reads http://dservices.arcgis.com/arcgis/services/V6ZHFr6zdgNZuVG0/JapanPrefectures2018/WFSServer, which is not correct. The value needs to be http://dservices.arcgis.com/V6ZHFr6zdgNZuVG0/arcgis/services/JapanPrefectures2018/WFSServer.

I attempted publishing a WFS Layer using a hosted feature layer and it produces the same error. I also tried publishing a WFS service from ArcGIS Pro, which works perfectly, I'm guessing because the Namespace is set as an option when publishing via Pro.

Any ideas? Is this a bug? Something I've missed? Something else?

Hi Kevin,

I tested this on an in-house WFS, created from a hosted feature layer in ArcGIS Online, and was able to reproduce the issue when sending a GetFeature request. I've logged this as BUG-000129387. I would recommend getting in contact with Esri Support to attach your customer number. Let me know and I can assist with this process.

Also cross posting this to ArcGIS API for JavaScript‌ and Esri Leaflet‌ communities to see if any workarounds have been identified.

Hope that helps,

-Peter
