}

However, when it launches php artisan clear-compiled the following error appears:

[BadMethodCallException]
Method filter does not exist.

Without any further information. As I understand, filter was deprecated, but I do not use filters in my routes.php. If I try to load any page, here is the exception I am getting:

    BadMethodCallException in Macroable.php line 74:
    Method filter does not exist.

Could you please help me to get rid of this error? All the stack trace references the internal files which I do not want to edit manually, and I am not sure how to fix that
