I think that the issue is in the async initialization logic of the `SpringDelegatingLambdaContainerHandler` ## Here: https://github.com/aws/serverless-java-container/blob/4696691989cfcd5d8957dbdfc280018aa267c8ba/aws-serverless-java-container-springboot3/src/main/java/com/amazonaws/serverless/proxy/spring/SpringDelegatingLambdaContainerHandler.java#L52-L63 ## Also here: https://github.com/aws/serverless-java-container/blob/4696691989cfcd5d8957dbdfc280018aa267c8ba/aws-serverless-java-container-springboot3/src/main/java/com/amazonaws/serverless/proxy/spring/SpringDelegatingLambdaContainerHandler.java#L73-L90 ## Spring Code: The `deduceMainApplicationClass` method use the `StackWalker`...

It seems that it's registering all controllers into the `org.springframework.cloud.function.serverless.web.ServerlessServletWebServerFactory` but the handler search into `com.amazonaws.serverless.proxy.spring.embedded.ServerlessServletEmbeddedServerFactory` So they exists multiple bean of the same interface type. Maybe the problem is...

I tried to force define/override those beans to always using the `com.amazonaws.serverless.proxy.spring.embedded.ServerlessServletEmbeddedServerFactory`: # Bean ```java @Bean public ServletWebServerFactory test() { return new ServerlessServletEmbeddedServerFactory(); } ``` # Log ``` 14:23:50.159 [main]...
