I'm developing a setting page for my widget. To debug it, I consulted the guide again and found this advice:
During development, use http://your host/webappbuilder/?appid=stemapp to directly access your widget. This URL helps test the configuration page of the widget. |
So I tried to open my builder with ?appid=stemapp query string. I got the list of my apps as though there was no query string. The only difference is that when I open an app from this page the loading lasts forever, not few seconds as when opened from the normal WAB root. This doesn't seem to be the direct access for my widget. Google on
