Webpack 5 no longer automatically includes polyfills for Node-specific objects like Buffer and process. However,
it's possible that your project, or one of its dependencies, still requires access to these variables. If so, you can
force Mix to include the necessary Node polyfills via the legacyNodePolyfills` option.
mix.options({
legacyNodePolyfills: true
});Keep in mind that this might result in a slightly larger bundle. If possible, take the necessary steps to eventually
remove these references from your front-end code - and then turn off legacyNodePolyfills to reduce your bundle size.
