Doing AutoExtract with PHP Curl

I am trying to extract content from a url with php. 

$curl = curl_init();
curl_setopt_array($curl, [
  CURLOPT_HTTPHEADER => [
    'Content-Type: application/json',
    'APIKEY: myapikeymyapikey'
  ],
  CURLOPT_RETURNTRANSFER => 1,
  CURLOPT_URL => 'https://autoextract.scrapinghub.com/v1/extract',
  CURLOPT_POST => 1,
  CURLOPT_POSTFIELDS => [
    'url' => 'https://blog.scrapinghub.com/gopro-study',
    'pageType' => 'article'
  ]
]);
$resp = curl_exec($curl);
curl_close($curl);
return $resp;

I get the error
