When I am migrating from springboot 3.1.6 to 3.2.0 I am facing the exact issue mentioned in https://github.com/spring-projects/spring-boot/issues/38636

The issue occurs only during deploying to prod but not on my local which is a windows machine.

I am having the below class and dependency which seems to be causing the issue.

public class SwaggerConfig implements WebFluxConfigurer

org.springdoc springdoc-openapi-starter-webflux-ui 2.0.4

Error

Despite its name, springdoc is not a project supported by the Spring team. You should report that against the project directly and probably upgrade to a version that actually supports Spring Boot 3.2.
