Error when no schedules exist

[sabbyanandan]

See:

Build: 2.8 SNAPSHOT on K8s.

@cppwfs The issue is there is no platform define (basic setup on minikube).
The issue affect all the schedule pages (creation, view, ...) since we are not able to have a list of platforms.

{
  "_links": {
    "self": {
      "href": "http://localhost:4200/tasks/platforms?page=0&size=1000"
    }
  },
  "page": {
    "size": 1000,
    "totalElements": 0,
    "totalPages": 0,
    "number": 0
  }
}

🤔 I just did a 2.8 deployment to TKS using our packaging scripts and there was no issue
@sabbyanandan How did you deploy your SCDF?

[sabbyanandan]

SCDF4K8s .. v1.2.1 on Minikube.

[cppwfs]

is investigating. This is not a scheduler issue. There is an issue with the 2.8 snapshot that it is not retrieving properties from the configmaps when running on minikube. This started after we upgraded to the latest Spring Cloud release.

On 1.3 SNAPSHOT in TAS, I get this error again.

This task in my test is manually launched, and not schedule driven. And, yet, when going to Tasks detail page, I get this NPE.
