After the latest update of PHP Intelephense that I get today, the intelephense keep showing an error for an undefined symbol for my route (and other class too), there is no error like this before and it's bothering me.

Here is the error screenshot :

enter image description here

And this is my code :

Route::group(['prefix' => 'user', 'namespace' => 'Membership', 'name' => 'user.'], function () {
    Route::get('profile', 'ProfileController@show')->name('profile.show');
    Route::patch('profile', 'ProfileController@update')->name('profile.update');
    Route::patch('change-password', 'ChangePasswordController@change')->name('change-password');
    Route::get('role', 'ProfileController@getRole')->name('profile.role');
    Route::get('summary', 'SummaryController@show')->name('summary');
    Route::get('reserved', 'AuctionController@reservedAuction')->name('reserved');
});

Actually there's no error in this code but the intelephense keeps showing an error so is there a way to fix this?

Intelephense 1.3 added undefined type, function, constant, class constant, method, and property diagnostics, where previously in 1.2 there was only undefined variable diagnostics.

Some frameworks are written in a way that provide convenient shortcuts for the user but make it difficult for static analysis engines to discover symbols that are available at runtime.

Stub generators like https://github.com/barryvdh/laravel-ide-helper help fill the gap here and using this with Laravel will take care of many of the false diagnostics by providing concrete definitions of symbols that can be easily discovered.

Still, PHP is a very flexible language and there may be other instances of false undefined symbols depending on how code is written. For this reason, since 1.3.3, intelephense has config options to enable/disable each category of undefined symbol to suit the workspace and coding style.

These options are: intelephense.diagnostics.undefinedTypes intelephense.diagnostics.undefinedFunctions intelephense.diagnostics.undefinedConstants intelephense.diagnostics.undefinedClassConstants intelephense.diagnostics.undefinedMethods intelephense.diagnostics.undefinedProperties intelephense.diagnostics.undefinedVariables

Setting all of these to false except intelephense.diagnostics.undefinedVariables will give version 1.2 behaviour. See the VSCode settings UI and search for intelephense.
