`import-wms-drawing` fails in GIS General Examples model with Internal Server Error (HTTP code 500)

[EwoutH]

In the GIS General Examples model the download-background-image fails when calling gis:import-wms-drawing with the following error message:

Extension exception: Unable to fetch wms image:
http result code 500 (Internal Server Error) (URL: https://ows.terrestris.de/osm/service?Format=image/jpeg&Transparent=TRUE&Version=1.1.1&SRS=EPSG:4326&BBOX=-180,-90,62069,180,90,62069&Request=GetMap&Service=wms&Height=292&Layers=OSM-WMS&Width=580&Styles=)
error while observer running GIS:IMPORT-WMS-DRAWING
  called by procedure DOWNLOAD-BACKGROUND-IMAGE
  called by Button 'download-background-image'

In this example this code is executed:

to download-background-image
  if-else projection = "WGS_84_Geographic" [
    gis:import-wms-drawing "https://ows.terrestris.de/osm/service?" "EPSG:4326" "OSM-WMS" 0
  ] [
    show "Only WGS_84_Geographic projections are supported. Please Change to WGS_84_Geographic in the top left drop-down."
  ]
end

And here is the full error message with internal details:

It could have to do with an API change in the ows.terrestris.de service, but I'm not sure.

I have the same problem. It seems to me that the empty parameter ´Styles´ is the issue here. It works on my Linux computer, but not on Windows.
It also worked with Netlogo 6.2.2, but since upgrading to Netlogo 6.3 it doesn't work any more.
