The usual culprit, in this case, is the unavailability of Boot's actuator endpoints at runtime.

More specifically, it is likely due to Spring Boot's /health and /info endpoints not accessible by SCDF at runtime.

With those dependencies packed in the classpath and upon the redeployment of the stream, you should be able to see the status as Deployed.
