The issue is the IPN handler returns a 500 error for unsupported or unknown IPN types. It occurs when Paypal sends IPN with some fields missing.
Steps to reproduce:
- Create a custom module that emulates all kinds of unknown IPN types from PayPal.
- Create at least one product.
- Configure PayPal Express with your own credentials.
- Place an order with Paypal Express.
- Run the PayPal emulator.
Expected results:
The application IPN handler ignores incorrect IPN types and doesn’t generate 500 errors:
Order 000000001: Status processing — HTTP 500
Actual results:
The application generates many 500 errors during processing incorrect IPNs and sporadically doesn’t process some orders if the expected fields are absent.
