Feign client and how to cast JSON-response to Application/Unencoded

I have a post method which can produce two types of response. The first one is with 200-OK status:

{"payment_uuid": "8f7f62e7-8ede-42d1-901c-68ae2651bc82"}

The second one is for an error:

["The user already has a subscription"]

I use FeignClient, my current type of a response is ResponseEntity<T>. How can I check, is the body has a JSON type with a payment_uuid field or with a response description? Do I need to change response type of my method?

I think you could implement an error decoder and catch the thrown exception inside an @ControllerAdvice. This way, you could define your POJO (which has payment_uuid field) in ResponseEntity<T> without worrying about the error description, because it'll be handled by the error decoder.
