See discussion in https://github.com/openshift/console/issues/2136. This happens when there is a template resource with `spec.template` but no `spec.template.spec` property.
This is only a problem in the 3.x console.
Verified this bug. Now the web console can handle template with resource `spec.template` correctly. OpenShift Master: v3.11.135 Kubernetes Master: v1.11.0+d4cacc0 OpenShift Web Console: v3.11.135
