Uncaught ErrorException: Return type of cebe\openapi\spec\Paths::offsetExists($offset) ...

[b166er]

I'm confused about this exception and have no idea how to resolve it. After doing some testing, I can't figure out what the problem is.

my test-case:

<?php

namespace Tests\Feature;

use Tests\TestCase;
use Spectator\Spectator;

class RootTest extends TestCase {

    /**
     * A basic test example.
     *
     * @return void
     */
    public function testGetRootPath() {
        Spectator::using('test.yaml');
        $response = $this->get('/');
        $response->assertStatus(301);
    }

}

my /routes/api.php:

// root move to First API
Route::get('/', function () {
    return redirect()->route('test.index', [], Response::HTTP_MOVED_PERMANENTLY);
})->name('root');

my test.yaml

openapi: 3.0.0
info:
  version: 1.0.0
  title: TestAPI
paths:
    "/":
        "get":
            summary: "Root Path"
            tags:
                - root
            responses:
                "301":
                    description: "Moved permanently to Index"

if i execute this small php-code i get same exception:

namespace App\Http\Controllers;
use cebe\openapi\spec\Paths;
use App\Http\Controllers\Controller;

class TestController extends Controller {
  public function test() {
        $input = ['/' => [
                'get' => [
                    'summary' => 'Root Path',
                    'tags' => [
                        0 => 'root'
                    ],
                    'responses' => [
                        301 => [
                            'description' => 'Moved permanently to Index'
                        ]
                    ]
                ]
        ]];
        $test = new Paths($input);
        var_dump($test);
  }
}

any ideas? maybe my test.yaml schema has a bug or is malformed?

ok, sorry, nvm, i found the bug, it's my php 8.1, it's not safe for phpunit: cebe/php-openapi#123

@b166er Thanks, I'll see if I can get it to be PHP 8.1 compatible.
