Hello guys please I have a problem in adding a geoprocessing custom widget..I only have arcgis online and arcgis server installed ..I don't have portal for arcgis..I shared this geoprocessing service and I can see it in my localhost gis server...I can even select it to be added as a custom widget in web appbuilder..but when I select it and click on "next" I got this message "choose a geoprecessing task"
