"Uncaught Error: Function name must be a string" when matching on a callback

[gturri]

Hi,

I'm trying to follow the 2nd snippet of the doc here https://github.com/InterNations/http-mock/blob/main/doc/stubbing.md but I get an error. I'm not sure if I'm doing something wrong or if there is an issue and I would be thrilled if you can give me pointer to fix it.
Here is my code:

<?php
declare(strict_types=1);

use InterNations\Component\HttpMock\PHPUnit\HttpMockTrait;
use PHPUnit\Framework\TestCase;
use Symfony\Component\HttpFoundation\Request;

final class CalDAVUTest extends TestCase {
    use HttpMockTrait;
    public static function setUpBeforeClass() : void {
        static::setUpHttpMockBeforeClass('8082', 'localhost');
    }
    public static function tearDownAfterClass() : void {
        static::tearDownHttpMockAfterClass();
    }
    public function setUp() : void {
        $this->setUpHttpMock();
    }
    public function tearDown() : void {
        $this->tearDownHttpMock();
    }

    public function test_doc(){
        $this->http->mock
            ->when()
                ->callback(
                    static function (Request $request) {
                        return $request->getMethod() === 'GET' && $request->getPathInfo() === '/resource';
                    }
                )
            ->then()
                ->callback(
                    static function (Response $response) {
                        $response->setBody('response');
                    }
                )
            ->end();
        $this->http->setUp();


        $curl = curl_init("http://localhost:8082/resource");
        curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
        curl_exec($curl);
    }
}

and here is the error I have:

1) CalDAVUTest::test_doc
HTTP mock server standard error output should be empty
Failed asserting that two strings are identical.

Here is the relevant part of my composer.json:

    "require-dev": {
        "phpunit/phpunit": "^9.5",
        "internations/http-mock": "^0.14.0"
    }

(and in my composer.lock I see that I'm using jeremeamia/superclosure version 2.4.0)

Does this error rings a bell?
