Testing error on Laravel Forum

I'm trying to set up Edit Post functionality in the tutorial project https://laracasts.com/series/build-a-forum-with-laravel I am working on a clone of branch episode_51; nothing changed at all except I've added extra Post resource routes edit and update, as well as a new test file EditPost.php.

Here's my web.php route:

Route::middleware([
    'auth',
    config('jetstream.auth_session'),
    'verified',
])->group(function () {
    Route::get('/dashboard', function () {
        return Inertia::render('Dashboard');
    })->name('dashboard');

    Route::resource('posts', PostController::class)->only(['create', 'store', 'edit', 'update', 'destroy']);
    Route::resource('posts.comments', CommentController::class)->shallow()->only(['store', 'update', 'destroy']);

    Route::post('/likes/{type}/{id}', [LikeController::class, 'store'])->name('likes.store');
    Route::delete('/likes/{type}/{id}', [LikeController::class, 'destroy'])->name('likes.destroy');
});

And here's my EditPost.php test:

<?php
use App\Models\Post;
use function Pest\Laravel\get;

it('requires authentication', function () {
    get(route('posts.edit', [Post::factory()->create()]))->assertRedirect(route('login'));
});

Why am I getting this error:
