I\'m working in VS Code and started getting this error yesterday. All of my json files have this error, not just a few. If I remember right there was an update to the program
I'm behind my company's proxy which I don't know the details because it's everything automatic, and this problem have bug me for some time.
I'm not sure whether this is an universal solution but according to this issue, the http.proxySupport setting is defaulting to "override". I turn this setting off and the errors disappeared.
"http.proxySupport": "off"
