¿Cómo convierto este resultado en una matriz de JavaScript?

HTTP/1.1 200 OK Fecha: sábado, 02 de octubre de 2021 09:19:28 GMT Tipo de contenido: application/json Longitud del contenido: 796 Conexión: keep-alive

Pensé que sería tan simple como PHP codificarlo, luego Javascript usando JSON.parse, pero luego aparece el error Uncaught SyntaxError: Unexpected token H en JSON en la posición 0

Código PHP:

 $payload = http_build_query(array( 'grant_type' => 'password', 'username' => $username, 'password' => $password )); $ch = curl_init(); curl_setopt($ch, CURLOPT_URL,'https://api.trustpilot.com/v1/oauth/oauth-business-users-for-applications/accesstoken'); //Url curl_setopt($ch, CURLOPT_POST, 1); curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); curl_setopt($ch, CURLOPT_POSTFIELDS, $payload); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_HEADER, true); curl_setopt($ch, CURLOPT_HTTPHEADER, array( 'Authorization: Basic ' . base64_encode($apiKey . ':' . $secretKey), 'Content-Type: application/x-www-form-urlencoded' )); $content=curl_exec($ch); if (curl_error($ch)) { $error_msg = curl_error($ch); echo json_encode($error_msg); } else { echo json_encode($content); } curl_close($ch);

Código AJAX:

 $.ajax({ type: "POST", url: "api-test-access-token.php", dataType: "JSON", success: function (response, textStatus, xhr) { var jsonData = JSON.parse(response); console.log(response); } })
