I'm trying to use visual studio code to debug my custom web app builder widget. I have set up my dev environment out site of the install directory of C:\WebAppBuilderForArcGIS. Then I use the scaffolding created by esri-appbuilder-js generator to run grunt and copy my files into the appropriate directories in WebAppBuilderForArcGIS. My question is how can I now use Visual Studio Code to step through and debug my code? If I use the launch config below then the application page doesn't fully load. The weird thing is that the moment I detach the visual studio code debugger then it finishes loading.
