+In this quickstart, you'll create a publisher microservice and a subscriber microservice to demonstrate how Dapr enables a publish-subcribe pattern. The publisher will generate messages of a specific topic, while subscribers will listen for messages of specific topics. See [Why Pub-Sub](#why-pub-sub) to understand when this pattern might be a good choice for your software architecture.

+                return new ResponseEntity<>("successful",
+                        HttpStatus.OK);
+            } catch (Exception e) {
+                throw new RuntimeException(e);


Is it normal to show try catch with a rethrow? or just cut the try catch?

I think yes, it is fine to write and here I wanted to throw if there is any unchecked exception happened like the cloudEvent.getData comes out to be null.
