Someone any time see this error when try to run the template locally? I follow the steps in the docs and I try to run "npm start" and I see this error:
Uncaught Error: Module parse failed: Unexpected token (2013:23)
You may need an appropriate loader to handle this file type, currently no loaders are configured to process this file. See https://webpack.js.org/concepts#loaders
| unregister() {
| document.removeEventListener("click", this.handleClickOutside);

    this.darkMedia?.removeEventListener("change", this.darkMediaCallback);

| this.unobserve();
| }
