Sample

@SpringBootConfiguration
public class FuncApplication implements ApplicationContextInitializer<GenericApplicationContext> {
	Region awsRegion = Region.US_EAST_1;

	public static void main(String[] args) throws Exception {
		FunctionalSpringApplication.run(FuncApplication.class, args);
	}

	public Function<Request, Response> function() {
		GetSessions sessions = new GetSessions("sessions",DynamoDbClient.builder().region(awsRegion).build());
		return value -> sessions.apply(value);
	}

	@Override
	public void initialize(GenericApplicationContext context) {
		context.registerBean("getSessions", FunctionRegistration.class,
			() -> new FunctionRegistration<Function<Request, Response>>(function())
                .type(FunctionTypeUtils.functionType(Request.class, Response.class)));
	}
}

Perhaps you can provide a reproducible sample as I can not reproduce it. Also may be something is wrong with your configuration.

In any event here is a working native sample , so please take a look - https://github.com/spring-cloud/spring-cloud-function/tree/main/spring-cloud-function-samples/function-sample-aws-native
