PHP单元测试失败，并发布请求

Question

我正在尝试使用symfony 5.1和php单元版本7.5.20，php版本7.4.3进行单元测试 但这无法发布请求 错误X-Debug-Exception The parameter 406 must be defined

Symfony\Component\DependencyInjection\Exception\InvalidArgumentException: The parameter "406" must be defined.

我尝试过的示例代码

public function testCreatePost()
{
    $client = static::createClient();
    $client->request(
        'POST',
        '/api/install',
        [],
        [],
        [
            'CONTENT_TYPE' => 'application/json',
            'HTTP_ACCEPT' => 'application/json',
            'HTTP_HOST'       => '192.168.1.2',
            'SERVER_NAME'       => '192.168.1.2',
            'HTTP_SERVER_PORT' => 8085,
            'HTTP_USER_AGENT' => 'MySuperBrowser/1.0',
        ],
        '{}'
    );

   // $request = $client->getRequest();
    $response = $client->getResponse();
    dump($response);
    exit;
    $this->assertEquals(200, $client->getResponse()->getStatusCode());
