I would like to use the add data widget on my application created with web app builder for developper.
I have this error : DOMException: Failed to execute 'open' on 'XMLHttpRequest': Invalid URL , when I add a wms service like this :
https://geo.fr.ch/ags/services/OpenData/Forages_lies_a_des_sites_pollues/MapServer/WMSServer?request...
it works with an app builder application hosted on arcgis online, but not with my application published on another server.
does a special setting need to be made on my server?
Thanks for your help
