I am trying to read this wms-service/url using the featurereader (espg 3857): https://geoservices.knmi.nl/adaguc-server?DATASET=RADAR&SERVICE=WMS&&SERVICE=WMS&VERSION=1.3.0&REQUEST=GetMap&LAYERS=RAD_NL25_PCP_CM&WIDTH=1131&HEIGHT=489&CRS=EPSG%3A3857&BBOX=-199509.20245398767,6500000,1419509.2024539877,7200000&STYLES=radar%2Fnearest&FORMAT=image/png&TRANSPARENT=TRUE&&time=2022-01-05T14%3A40%3A00Z

 

Somehow this gives me the wrong return, what's more: If I change the date/time the result stays the same, which should not happen

 

Using the exact same url in the httpcaller and saving it as a .png gives me the proper result (but i dont want to be saving files).

 

Any clue what i might be doing wrong?

I can't recreate. Using the WMS reader gives me the same result as the HTTP Caller and ImageFetcher transformers. Changing the date gives different output

That is really weird. Could you share your feauturereader settings?

My settings are as per your screenshot and adding the RasterToPolygonCoercer after results in 801 features. Might be a different version of the feature reader? I'm working in 2021.2 with version 13 of the FeatureReader
