my java code is:
@PostMapping("/stripe/webhooks")
@ResponseStatus(HttpStatus.ACCEPTED)
public String handleStripeWebhook(@RequestBody String payload, @RequestHeader("Stripe-Signature") String sigHeader) throws Exception {
Event event = null;
try {
event = ApiResource.GSON.fromJson(payload, Event.class);
} catch (JsonSyntaxException e) {
// Invalid payload
ResponseEntity.status(HttpStatus.BAD_REQUEST).body(null);
return "";
}
if (stripeEndpointSecret != null && sigHeader != null) {

        Subscription subscription = null;
        try {
            event = Webhook.constructEvent(
                    payload, sigHeader, stripeEndpointSecret
            );
        } catch (JsonSyntaxException e) 
            return "";
        } catch (SignatureVerificationException e) {
            return "";
        }
        // Deserialize the nested object inside the event
        EventDataObjectDeserializer dataObjectDeserializer = event.getDataObjectDeserializer();
        if (dataObjectDeserializer.getObject().isPresent()) {
            subscription = (Subscription) dataObjectDeserializer.getObject().get();
        } else {
            // Deserialization failed, probably due to an API version mismatch.
            // Refer to the Javadoc documentation on `EventDataObjectDeserializer` for
            // instructions on how to handle this case, or return an error here.
            log.error("deserialize failed for {} ", dataObjectDeserializer.getRawJson());
        }

but this segment (if (dataObjectDeserializer.getObject().isPresent())) return false

Hi, let me help you with this.

Do you know if no other errors are thrown? Can you print the event object?

[restive vapor]

I got event but "dataObjectDeserializer.getObject().isPresent()" return false value

[agile haven]

What do you use to print the object?

[restive vapor]

I run server in debugging mode and this event is value of debugging mode

[fallow glacier]

Which version of the Java SDK are you using? https://github.com/stripe/stripe-java

[restive vapor]

<dependency>
<groupId>com.stripe</groupId>
<artifactId>stripe-java</artifactId>
<version>26.7.0</version>
</dependency>

[fallow glacier]

Which line in your code returns this JSON?

[restive vapor]

I have breakpoint at this line:if (dataObjectDeserializer.getObject().isPresent())
I get this event from debugger thread & variables

[fallow glacier]

Hmm this kind of issues normall signify a mismatch between the API version of the event/webhook and the SDK.

But that doesn't seem to be true here – 26.7.0 is fixed to 2024-06-20 version which the example event you've shared was generated with

[restive vapor]

can you suggest me java sdk version and api version for resolving this issue?

[fallow glacier]

I don't think that's the root cause here as the version of the SDK version you're using is locked to the same API version of the event (as noted above)

Checking with a colleague

Can you try and use the deserializeUnsafe method as outlined here?

As an example:

subscription = (Subscription) dataObjectDeserializer.deserializeUnsafe();

Also, can you make sure your in that your integration code is indeed using version 26.7.0 of the SDK? Recent requests from your account are using 25.x.x

That would result in the API version mismatch and the issues you're seeing. Maybe you need to re-sync Gradle?

[restive vapor]

dataObjectDeserializer.deserialize() hast this error:
eserialize()' has private access in 'com.stripe.model.EventDataObjectDeserializer'

[fallow glacier]

It's deserializeUnsafe()

[restive vapor]

I upgraded today for resolving this issue

[fallow glacier]

Well looking at API requests made today (like the above) I don't think it's actually upgraded the SDK version compiled in your code. You likely need to rebuild and/or resync the dependencies
