We are having problems using WFS Services in GML format in ArcGIS Pro, ArcGIS Desktop and ArcGIS Online.
Here is a sample service which fails:
In ArcGIS Pro 2.3.3 with Data Interopability installed and enabled the service is successfully added to catalog, but when layers are added the following error is shown:
"schema/element - no one element found." (See attached screenshot)
In ArcGIS Desktop 10.7 with Data Interopability installed and enabled it gives the error shown in the screenshot.
In ArcGIS Online it enumerates the layers and fails with message "Can't be added". (See attached screenshots)
QGIS also gives a error. Check the screenshot.
Do you have any more input on this issue? We have the same error with a lot of different services from different providers here in Norway.
