Using the web console on the RH Developer Sandbox, created the most basic Knative Service (KSVC) using the default suggested, ie image openshift/hello-openshift.

Then tried to change the displayed icon using the web UI and an error about Probes was displayed. See attached images.

Using the web console on the RH Developer Sandbox, created the most basic Knative Service (KSVC) using the default image openshift/hello-openshift.

Then used the webUi to edit the KSVC sample to change the icon used from an OpenShift logo to a 3Scale logo for instance.

When saving from this form an error was reported: admission webhook 'validation webhook.serving.knative.dev' denied the request: validation failed: must not set the field(s): spec.template.spec.containers[0].readiness.Probe

Either a failure message related to changing the icon, or the icon change to take effect
