Yahoo OATH DSP API - 创建报告会导致问题

Question

I successfully get access token and then try to create report using this code:

$post = '{
        "reportOption": {
            "timezone": "Europe/London",
            "currency": 1,
            "dimensionTypeIds": [ 5 ],
            "metricTypeIds": [ 44, 1, 2, 23, 11, 41, 43 ]
        },
        "intervalTypeId": 1,
        "dateTypeId": 2,
        "startDate": "2019-01-30T00:00:00",
        "endDate": "2019-01-30T11:59:59"
    }';

    $url = 'http://api-sched-v3.admanagerplus.yahoo.com/yamplus_api/extreport/';

            $curl = curl_init();

            $options = array(
                CURLOPT_URL => $url,
                CURLOPT_HTTPHEADER => array(
                    'Content-Type: application/json',
                    'X-Auth-Method: OAUTH',
                    'X-Authorization ' . json_decode($this->token)->access_token
                ),
                CURLOPT_TIMEOUT => 600,
                CURLOPT_ENCODING => "",
                CURLOPT_RETURNTRANSFER => 1,
                CURLOPT_MAXREDIRS => 3,
                CURLOPT_HTTPAUTH => CURLAUTH_ANY,
                CURLINFO_HEADER_OUT => true,
                CURLOPT_CUSTOMREQUEST => 'POST',
                CURLOPT_SSL_VERIFYPEER => false,
                CURLOPT_POSTFIELDS => $post
            );

            curl_setopt_array($curl, $options);

            $res = curl_exec($curl);

            print_r($res);

Unfortunately it doesn't let me authorise even though the account I am using has a full access. I keep getting this response:

{
   status: 401,
   message: "HTTP 401 Unauthorized",
   requestId: "1549288356177-a3b-180-t1",
   requestUrl: "http://api-sched v3.admanagerplus.yahoo.com/yamplus_api/extreport/",
   requestBody: ""

}

What is wrong here?
