WFS GetFeature: NamespaceUri mixup

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=""
 xmlns:wfs="" xmlns:gml="" 
 xmlns:xlink="" xmlns:xsi=""

The value reads, which is not correct. The value needs to be

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,
