Start by comparing the API Gateway and ALB configurations for the Spring Boot 2.2.1 application described in the issue, focusing on the logged POST request and its 302 Location response. The issue does not name source files or tests and cannot provide reproduction steps; done means identifying why ALB returns the redirect and making it return the same response as API Gateway.
