Keycloak发送电子邮件重置密码返回500 Internal Server Error（GuzzleHTTP）

Question

我使用GuzzleHTTP编写代码：

    $clientToken = new \GuzzleHttp\Client();
    $responseToken = $clientToken->request('post', 'https://myserwer.com/auth/realms/testrealm/protocol/openid-connect/token', [
        'headers' => [
            'User-Agent' => $_SERVER['HTTP_USER_AGENT'],
            'Accept'     => 'application/json'
        ],
        'form_params' => [
            'username' => 'user-test',
            'password' => 'testpassword',
            'grant_type' => 'password',
            'client_id' => 'test-api',
            'client_secret' => getenv("SECRET_KEYCLOAK")
        ]
    ]);

    $json = json_decode($responseToken->getBody(), true);
    $access_token = $json['access_token'];

    $client = new \GuzzleHttp\Client();
    $response = $client->request('put', 'https://myserwer.com/auth/admin/realms/testrealm/users/a9...d1/execute-actions-email', [
        'headers' => [
            'Authorization' => 'Bearer ' . $access_token,
            'User-Agent' => $_SERVER['HTTP_USER_AGENT'],
            'Content-Type' => 'application/json',
            'Accept' => 'application/json'
        ],
        'form_params' => [
            json_encode([
                'actions' => ['UPDATE_PASSWORD'],
            ])
        ]
    ]);

    $status = $response->getStatusCode();
    $header = $response->getHeaderLine('content-type');
    $body = $response->getBody();
    return response()->json($body);

我拥有服务授权，但我不知道我是否发送了所有数据。我使用方法PUT发送： 主体中的授权，用户代理，内容类型，接受和操作。 但是服务器仍然返回：
