I’m trying to track down some lighting problems in a project using 4.0.3 and set up the scenario in the playground, but when I switch from “latest” to “4.0.3” the playground page locks up.
The error is in monacoCreator.js: TypeError: Cannot read property ‘setValue’ of null
this.jsEditor is null
EDIT: It seems that every playground wants to use 4.0.3 now and they’re all crashing (I can’t use the playground, YIKES!)
I’m guessing it’s a cookie so I’ll clear the last hour or so and hopefully that will fix this part of the problem
