Backend application runs on Spring boot, Gradle – 8.1.1 and Kotlin – 1.8.21. Till Spring boot 3.1.12 all API’s are working fine. When I upgrade to 3.2.0, only one API is failing with

<200 OK OK,Input payload not found,[Content-Type:”text/plain; charset=utf-8″, Transfer-Encoding:”chunked”>

No changes done in API. I can see this error only upgrading to 3.2.0. Any clue please?
