Hello @JShi_EsriStaff - have you following or have seen this post:
I ask simply because we have a failure somewhere in our upgrade from 11.1 to 11.2, and apparently not everything installed because I can't even launch the InstantGallery page. . . the TS can't find other js and node modules... I'm working with support but if you have anything you could add my support case number is
Esri Case #03592799 - 11.2 Instant Apps configuration page will not display
Thanks-
