Description David Caldwell 2017-08-31 13:39:21 UTC 
Description of problem:
Executing 'oc get --all-namespaces --output=json projectrequests' causes panic. The combination of 'projectrequests' type and -o to yaml or json seems to cause the problem.

Version-Release number of selected component (if applicable):
3.5
3.6
(Customer logged bug with OCP 3.6.1 but I can reproduce using same command using OCP 3.5)

How reproducible:
Execute 'oc get --all-namespaces --output=json projectrequests' on the CLI 

Steps to Reproduce:
1. Log in to master
2. Execute 'oc get --all-namespaces --output=json projectrequests'
3. 

Actual results:
$ oc get --all-namespaces --output=json projectrequests
panic: interface conversion: runtime.Object is *unversioned.Status, not *runtime.Unstructured
