Convert string to javascript array calling AJAX php curl call

Question

How do I convert this result to a javascript array?

HTTP/1.1 200 OK Date: Sat, 02 Oct 2021 09:19:28 GMT Content-Type: application/json Content-Length: 796 Connection: keep-alive

{ "refresh_token_expires_in" : "7779999", "refresh_token_status" : "approved", "api_product_list" : "[trustpilot-client-api, public_data]", "app_enduser" : "APIID", "api_product_list_json" : [ "trustpilot-client-api", "public_data" ], "organization_name" : "trustpilot", "developer.email" : "[email protected]", "token_type" : "BearerToken", "issued_at" : "1633166368319", "client_id" : "CLIENTID", "access_token" : "ACCESSTOKEN", "refresh_token" : "TOKENNAME", "application_name" : "NAME6", "scope" : "", "refresh_token_issued_at" : "1633166368319", "expires_in" : "359999", "refresh_count" : "0", "status" : "approved" }

I thought it would be as simple as the PHP encoding it, then the Javascript using JSON.parse but I then get the error Uncaught SyntaxError: Unexpected token H in JSON at position 0

PHP Code:

$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);

AJAX Code:

$.ajax({
    type: "POST",
    url: "api-test-access-token.php",
        dataType: "JSON",
        
        success: function (response, textStatus, xhr) {

            var jsonData = JSON.parse(response);
            console.log(response);


        }
    })

You need to set CURLOPT_HEADER above to false (or remove the line) as it will add the headers to the output of curl_exec and of course this is not a valid JSON. $content will then just contain the body of the response.

From the PHP documentation (see https://www.php.net/manual/en/function.curl-setopt.php):

CURLOPT_HEADER  |  true to include the header in the output.
