JsonMappingException exception is throwing when retrieving a customer

[nnurmano]

The code was working with an older stripe version 3.5.0 library, but with the newest library it throws:

Caused by: com.fasterxml.jackson.databind.JsonMappingException: No serializer found for class com.stripe.net.StripeResponse and no properties discovered to create BeanSerializer (to avoid exception, disable SerializationFeature.FAIL_ON_EMPTY_BEANS) (through reference chain: com.stripe.model.Customer["lastResponse"])

Here is the code pieces:
In the serviceImpl class I retrieve Customer object via
customer = Customer.retrieve(currentAccount.getCustomerStripeId());

In the controller class:

         Customer currentCustomer = stripeService.findCustomerByUserId(id);

        //StripeResponse response = currentCustomer.getLastResponse();
        //System.out.println("the customer is " + response.body());
        //Customer card = APIResource.GSON.fromJson(response.body(), Customer.class);
        if (currentCustomer == null) {
            return new ResponseEntity<>(HttpStatus.NOT_FOUND);
        }
        return new ResponseEntity<>(currentCustomer, HttpStatus.OK);

This piece of code throws above error. When I re-write the method as below:

        Customer currentCustomer = stripeService.findCustomerByUserId(id);
        StripeResponse response = currentCustomer.getLastResponse();
        System.out.println("the customer is " + response.body());
        Customer customer = APIResource.GSON.fromJson(response.body(), Customer.class);
        if (currentCustomer == null) {
            return new ResponseEntity<>(HttpStatus.NOT_FOUND);
        }
        return new ResponseEntity<>(customer, HttpStatus.OK);

The customer is returned with no issues. What have changed in the library? Do I have to re-write my code base as above?

Hi @nomadus. I think this issue is caused by the addition of the lastResponse attribute on StripeObjects in version 5.24.0 (#421).

The library uses Gson as its JSON library, and using APIResource.GSON.fromJson() is indeed the canonical way of deserializing JSON payloads into Stripe objects.

You can go with your rewritten method, or alternatively you can configure Jackson to ignore transient fields with PROPAGATE_TRANSIENT_MARKER.

is this issue resolved yet ? I am getting the same exception just for passing ChargeCreateParams object to the charge.create() method. it works fine if I put spring.jackson.mapper.propagate-transient-marker=true in the properites file.
I am not implementing any of stripe interfaces and the below exception is thrown
"Type definition error: [simple type, class com.stripe.net.StripeResponse]; nested exception is com.fasterxml.jackson.databind.exc.InvalidDefinitionException: No serializer found for class com.stripe.net.StripeResponse and no properties discovered to create BeanSerializer (to avoid exception, disable SerializationFeature.FAIL_ON_EMPTY_BEANS) (through reference chain: com.stripe.model.Charge["lastResponse"])"

Hi @dagetachew. I don't think this issue can be solved from the stripe-java library. stripe-java uses Gson as its JSON library, not Jackson, so we cannot ensure that Stripe objects will play nicely with Jackson.

The proper way to fix this would be to never use Jackson to serialize or deserialize Stripe objects from/to JSON. You can use the following methods provided by the library instead:

// deserialization
Customer customer = APIResource.GSON.fromJson(json, Customer.class);

// serialization
String serialized = customer.toJson();

If you absolutely have to use Jackson, then setting PROPAGATE_TRANSIENT_MARKER to true is a simple workaround to avoid triggering an exception when serializing an object. You could also possibly write a custom Jackson serializer for StripeObject that simply delegates to stripeObject.toJson().

Thanks for this. My team is spiking out a Stripe solution with Spring and this info was very helpful.
