Hey, I've been following the example documentation provided, but started running into issues across the project when response was null, which resulted in exception while attempting to read messages. https://github.com/AuthorizeNet/sample-code-php/blob/master/TransactionReporting/get-transaction-details.php#L40 ``` Call to a member function getMessages() on null ``` ```php echo "ERROR : Invalid response\n"; $errorMessages = $response->getMessages()->getMessage(); echo "Response : " . $errorMessages[0]->getCode() . " " .$errorMessages[0]->getText() . "\n"; ```
