Uncaught SyntaxError: Unexpected token '<' When using create-react-app develop mode

Okay, it seems that I've figured it out. It was all serviceWorker's fault. I've added the following snippet and everything started working fine

if (!process.env.NODE_ENV || process.env.NODE_ENV === "development") {
    // dev code
    serviceWorker.unregister();
} else {
    // production code
    serviceWorker.register();
}
