General information

  • SDK/Library version: 1.14.0
  • Environment: sandbox
  • PayPal-Debug-ID values: It's a client-side error
  • Language, language version, and OS: Java 1.7.0_51 on Windows 10

Issue description

My current task is to improve the application Payment error handling.
Currently the application is simply catching all exceptions, logging and redirecting to a generic error page.
Now i need to catch the REST API error message to handle it properly.
So, i'm trying the negative testing (https://developer.paypal.com/docs/api/nt-rest/) to validate my error handling implementation, but i'm unable to reach the response error message due to a JSON Parse error.

I've implemented a simple proof of concept, the craziest JUnit i ever wrote, it will reproduce my issue almost automaticly:

Can you please put the code on a test repo instead? Also, what's your client Id so that we may be able to do more researching from the backend.

I noticed something:
The WebService JSON Response is:

{
    "name": "AMOUNT_MISMATCH",
    "message": "The totals of the cart item amounts do not match sale amounts.",
    "information_link": "https://developer.paypal.com/docs/api/payments/#errors",
    "details": "The amount total does not match the item amount totals."
}

But, the Error class is:

public class Error extends PayPalModel {

	private String name;

	private String message;

	private List<ErrorDetails> details;

	private String informationLink;

	private String debugId;

	private List<DefinitionsLinkdescription> links;

        [...]
}

The "details" property between JSON and Java model are inconsistent.
The JSON parser fail to parse the JSON property "details" from string to List<ErrorDetails> of Java model.

Do you have a debug ID for it?

No, because the server responded appropriately.
The SDK who failed to parse the server response.

Thanks for the details. I've opened https://github.com/paypal/PayPal-REST-API-issues/issues/197 to track this issue as the negative testing API is not returning a standard error response. We cannot change the Error object for backwards compatibility reasons, but the API should be fixed to return a standard response.

So, there's no other way to simulate it?

@leandrohsilveira I don't believe so. The negative test simulation was recently added as a beta. I've opened an internal issue as noted in https://github.com/paypal/PayPal-REST-API-issues/issues/197 to get this fixed.

Hi all, This just came to my team today. Apologies for the delayed response.
This beta was our first foray into a new method of negative testing simulation, and it was not initially built with SDK support in mind.

However, we are currently building a more comprehensive negative testing framework, and this is definitely something we will be taking into account.

As to the current method, and because of the experimental nature of it, we can't commit to additional development time, or bug fixes at this point.

I would be more than happy to have feedback sessions on what developers are looking for in a negative testing framework from PayPal. Please hit me up on twitter @LennyMarkus
