If you then fix the issue, the problems will go away (along with the yellow squiggle. This opens a panel with the problems in the current document: While there's a keyboard command for this, I normally open it by clicking the warning sign on the bottom left: You'll see the tooltip provides detailed explanations about the validation error. One is to just mouseover the yellow squiggle: If you actually type in the InvalidValue string I used above, you'll see it highlighted:

I've been using the first one, VSCode Map Preview, for a while now so I suggest installing that one. If you go ahead and click on "Search Marketplace", you'll find two (currently) suggested extensions: So while Code recognizes there's extensions out there that will help, for now it's going to treat it as just a text file.
