Error page with Laravel policy and authorization with User Model

This is my UserPolicy:

<?php
namespace AppPolicies;
use AppModelsUser;
use IlluminateAuthAccessHandlesAuthorization;
class UserPolicy
{
    use HandlesAuthorization;
    public function view(User $user, User $model)
    {
        return $user->id === $model->id;
    }
}

This is the AuthServiceProvider:

<?php
namespace AppProviders;
use AppModelsUser;
use AppPoliciesUserPolicy;
use IlluminateFoundationSupportProvidersAuthServiceProvider as ServiceProvider;

class AuthServiceProvider extends ServiceProvider
{
    /**
     * The policy mappings for the application.
     *
     * @var array<class-string, class-string>
     */
    protected $policies = [
        // 'AppModelsModel' => 'AppPoliciesModelPolicy',
        User::class => UserPolicy::class
    ];

    /**
     * Register any authentication / authorization services.
     *
     * @return void
     */
    public function boot()
    {
        $this->registerPolicies();

        //
    }
}

And finally the UserController

<?php

namespace AppHttpControllers;

use AppModelsUser;
use IlluminateHttpRequest;

class UserController extends Controller
{
    public function show(User $user)
    {
        $this->authorize('view', $user);
        return view('user.show', [
            'user' => $user,
        ]);
    }
}

I am trying to use $this->authorize('view', $user); to authorize but I am getting the “Something went wrong in Ignition!” error page.

I have already spent an entire day trying to figure out what I have done wrong. Can anyone please point out what’s wrong?
