When running the fabric8 maven plugin to build/deploy/run from local developer environment to an OpenShift 4.6 cluster, the plugin fails with an error below. This worked in OpenShift 4.5

The plugin creates the BuildConfig and kicks off the build on the OpenShift 4.6 cluster (so there is a workaround to deploy using 'oc new-app') but the plugin fails on the local developer terminal next on an cluster api service call
