After installing Laravel Socialite, Query scope method and relationships not working

I have a scope method "scopeUserResponse" in user model:

public function scopeUserResponse($query,$user_id)
{ 
    return $query->where('users.id' , $user_id)->select(
                'users.id as user_id',
                'users.username as user_name',
                'users.first_name as user_fname',
                'users.last_name as user_lname'
            );
}

I am calling it from controller, like:

$userdetail = User::userResponse($user->id)->first();

it was working fine but now its giving me error

Method Illuminate\Database\Query\Builder::userResponse does not exist.

Even my relationship methods are not working after installing Socialite.
