                a `Content-Type` header will **not** be parsed as JSON.

                This prevents potential cross-site request forgery (CSRF) attacks
                that exploit the browser's ability to send requests without a
                Content-Type header, bypassing CORS preflight checks. In particular
                applicable for apps that need to be run locally (in localhost).
