method getSubscriptionId() not defined .

[ipalenciab]

Hi expert, I'm using laravel and I'm creating a Recurring Billing in sandbox, After a few hour of fighting i literally copy and paste the sample code and just add my sandbox credentials to it sample: [(https://github.com/AuthorizeNet/sample-code-php/blob/master/RecurringBilling/create-subscription.php)]

I'm getting the error undefined method getSubscriptionId() by IntelliSense corrector.

the following line suppose to return a CreateTransactionResponse object , correct? :
$response = $controller->executeWithApiResponse( \net\authorize\api\constants\ANetEnvironment::SANDBOX);

if i create a var instance of CreateTransactionResponse , i can get the method but not with $response that suppose to be the same type.
so here it line 68 i got the erro:
echo "SUCCESS: Subscription ID : " . $response->getSubscriptionId() . "\n";
and I'm not able to get access to the SubscriptionId to store it.
any help please.

version informations:
I'm using php 8.2.14 authorizenet 2.0 laravel framework 8.83 the Recurring Billing is created and it response form the API is "Ok", but I'm not able to get the SubscriptionId due to this error.
