Azure Functions Error Debug: Running processor on exception: '/' is invalid after a value. Expected either ',', '}', or ']'

As it turns out, Azure Functions might not like "comments" in your host.json, and it will fail awkwardly.

  "version": "2.0",
  "functions": [
    "myfunc"
    //"myotherfunc" <--- THIS WILL BREAK THE FUNCTIONS APP
  ],
  "someMoreJsonHere" : { }

Console output:

Debug: Running processor on exception: '/' is invalid after a value. Expected either ',', '}', or ']'. Path: $.functions | LineNumber: xx | BytePositionInLine: xx.
