Steps to Reproduce:

1. Create a new Gatsby project, or clone from my repo
2. Open VSCode
3. Create a new jsconfig.json file if it does not exist
4. Problems panel will randomly show errors on the jsconfig.json file
   

The jsconfig.json file contains this:

{
    "compilerOptions": {
        "module": "commonjs",
        "jsx": "preserve",
        "baseUrl": "./src"
    },
    "include": ["src"],
    "exclude": [
        "node_modules",
        "**/node_modules/*",
        "node_modules/**/*",
        "public"
    ]
}

Does this issue occur when all extensions are disabled?: Yes

Reproduce the report with a Gatsby project in VS Code using the supplied jsconfig.json, then inspect the Problems panel diagnostics for that file. Done means the configuration no longer receives erroneous or random problems when the project is opened with extensions disabled.
