API->GetTLDPricing Does not show prices

I tried to get the domain price list and it only shows data currency

My code:

<?PHP

*/

// API Connection Details
$whmcsUrl = "https://***********";

// For WHMCS 7.2 and later, we recommend using an API Authentication Credential pair.
// Learn more at http://docs.whmcs.com/API_Authentication_Credentials
// Prior to WHMCS 7.2, an admin username and md5 hash of the admin password may be used.
$username = "*********";
$password = "************";

// Set post values
$postfields = array(
   'username' => $username,
   'password' => $password,
   'action' => 'GetTLDPricing',
   'responsetype' => 'json',
);

// Call the API
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $whmcsUrl . 'includes/api.php');
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 30);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($postfields));
$response = curl_exec($ch);
if (curl_error($ch)) {
   die('Unable to connect: ' . curl_errno($ch) . ' - ' . curl_error($ch));
}
curl_close($ch);

// Decode response
$jsonData = json_decode($response, true);

// Dump array structure for inspection
var_dump($jsonData);

My result:

array(1) {
 ["currency"]=>
 array(6) {
   ["id"]=>
   string(1) "1"
   ["code"]=>
   string(3) "MXN"
   ["prefix"]=>
   string(1) "$"
   ["suffix"]=>
   string(4) " MXN"
   ["format"]=>
   string(1) "2"
   ["rate"]=>
   string(7) "1.00000"
 }
}

Why do not the prices of domains leave? The documentation says otherwise: https://developers.whmcs.com/api-reference/gettldpricing/

Mine is doing the same.

Any feedback on this would be great.

Same Problem for me.

Same Problem for me.

it's supposedly a known bug.

A patch for this is included in v7.2.3
