Update payment in open-source QuickBooks PHP DevKit on GitHub - quickbooks

Question

I am using the open-source QuickBooks PHP DevKit on GitHub. I am trying to update a payment. But I am getting an error "ERROR!2030: [Invalid ID, Id should be a valid number. Supplied value:{-17}]"
Code I had given is shown below
First added code for update function in Quickbooks/IPP/Service/Payment.php like below:
public function update($Context, $realm, $IDType, $Object)
{
return parent::_update($Context, $realm, QuickBooks_IPP_IDS::RESOURCE_PAYMENT, $Object, $IDType);
}
After that in the payment_update.php page, I added the code as given below:
$IPP->version(QuickBooks_IPP_IDS::VERSION_3);
$PaymentService = new QuickBooks_IPP_Service_Payment();
$payments = $PaymentService->query($Context, $realm, "SELECT * FROM Payment where Id='27'");
$Payment = $payments[0];
$Payment->setPaymentRefNum("5Update");
if ($resp = $PaymentService->update($Context, $realm, $Payment->getId(), $Payment))
{
print('Updated the item name to ' . $Payment->getTotalAmt());
}
else
{
print('ERROR!');
print($PaymentService->lastError($Context));
}
Do I need to add any other changes in the class file for updating a payment. Please advise how can I update payment & line.

This was fixed in an update several months ago.
Please use the latest code from GitHub and you should be all set:
