How to run multiple deployments in ray serve 2.0

Routing with DAGDriver and serve.ingress

Thanks. I understand that works, but I specifically am interested with the case with both DAGDriver and @serve.ingress, because I want to be able to use FastApi wildcard routes, but also have some deployments that can be scaled independently. The question is really what specifically goes wrong with my example - why don’t we just get a 200 with “hello” as the response body?
