Error while trying to retrieve Session

[FMusic]

Hello,
I am using Spring Boot with Stripe and I get an error while trying to retrieve Session by it's id.

@GetMapping("/checkout-session/{sessionId}")
public Session checkoutSession(@PathVariable(value = "sessionId") String sessionId) {
    try {
       return Session.retrieve(sessionId);
    } catch (StripeException e) {
       return null;
    }
}

Exception:

Hello @FMusic,

Judging by the error message, I believe your code is retrieving the Session successfully, but the error is triggering because Spring Boot cannot figure out how to turn the Session object back into JSON.

A couple options:

• You can access the raw JSON (as a string) and do something like return Session.retrieve(sessionId).getLastResponse().body(); instead of returning the Session directly.
• You might have better luck if you tried to configure Spring Boot to use GSON instead of Jackson -- since GSON is the library that stripe-java uses internally to handle JSON deserialization. I'm not 100% sure this would work though.
• Worst case, you can write a Session class of your own with its own Jackson serializer, and manually populate it with the values you are interested in from stripe-java's Session. Not convenient at all, but might unblock you if you are just doing something simple.

All that said, it definitely would be nice if the code as you wrote it would Just Work with Spring Boot. Playing nicer with Jackson has come up before but is unfortunately not likely to happen soon.

Thank you @richardm-stripe this works for me by adding Session.retrieve(sessionId).getLastResponse().body()
you are right.
