HMR Update Failed
webpack's Hot Module Replacement could not apply a patch to the running application. This happens when the updated module or one of its ancestors cannot be hot-replaced (no `module.hot.accept` handler bubbles the change to the app root). The dev server falls back to a full page reload. To avoid the fallback, add `module.hot.accept()` boundaries around the module.
