Hi,

It seems that WfsV2FeatureSource adds “&propertyname=” to GetFeatures requests by default even if there are no values to be set to this parameter.

This empty “propertyname=” causes problems with some WFS server (depending on the server implementation) and those return BadRequest e.g with reason “WFS server error. Invalid PROPERTYNAME”.

Should that parameter be added only if there are some values to it ?

Br, Simo

Hi Simo,

It’s recreated and fixed in the latest beta131, pull the latest and have another try. This fix will also be available in v14.5 releasing next week.

Thanks,
