Just because it is in the official VSC repo does not necessarily make it right, it is clearly an invalid JSON file and the error message is displayed.

Showing the exact line number of the error is beyond this project's scope for now.

I'm currently using https://www.npmjs.com/package/strip-json-comments to remove the comments if any.

There are many online linters available, please check https://jsonlint.com/
