Using PyQGIS how can I request WFS data using GeoServer's viewparams request parameter?
I can use the viewparams request parameter to obtain the filtered WFS data I require via my web browser but not via PyQGIS.
The below returns the results I require via a browser and this appears to be valid WFS GML
(Where <LDS_API_KEY> is the auth key generated by registered users via https://data.linz.govt.nz/. Please let me know if you can help and don't want to register and perhaps I can generate a temporary key to share)

via PyQGIS when trying to create a WFS vector layer with the same URL with the viewparams I get a invalid layer:

@nmtoken. Sorry I should have explained. GeoServer is backward compatible with typename. There appears to be a bug with QGIS, whereby wfs requests using typenames fails but typename succeeds.
