Adding WMS service published by Geoserver

I am trying to add a wms map service published by Geoserver, but I get an error that says “Failed to initialize site. The error was: Unable to get property 'path' of undefined or null reference” when lunching the application

This is better elaborated with the screenshots below.

What might be the issue here?

Any help is appreciated,
