Spring Cloud Data Flow Local Server + Skipper Server: Error after undeploying streams

I trying to manage my streams on spring cloud data flow with skipper server.

I followed the instruction here:

https://docs.spring.io/spring-cloud-dataflow/docs/current/reference/htmlsingle/#getting-started-deploying-spring-cloud-dataflow

The app registration and stream definition/deployment goes quite well, but after I undeploy the deployed stream, I can't see any stream on the dashboard any more. The dashboard shows an error instead:

Could not parse Skipper Platform Status JSON:null

I have to restart the scdf server and skipper server in order to see my stream definition again. The version of the components are:

  • scdf local server: 1.6.0.RELEASE
  • skipper server: 1.0.8.RELEASE
  • metrics collector: kafka-10-1.0.0.RELEASE

Some operation details:

  1. I registered my app using scdf shell in skipper mode.
  2. I defined and depolyed my stream on the scdf dashboard. I undeployed the stream via the stop button on the dashboard, too.

How should I solve this problem?

We have recently observed this on our side, too, and it has been fixed! [see spring-cloud/spring-cloud-dataflow#2361]

We are preparing for a 1.6.1 GA release, but in the meantime, please feel free to pull the 1.6.1.BUILD-SNAPSHOT from Spring repo and give it a go.

If you see any other anomaly, it'd be great to have a bug report on the matter.
