Bug 1826808

@Abhishek, I'm not sure the steps to verified the bug, we should install Knative Eventing Operator first, right? 
I tried to install it in project, but failed.
Failed
CustomResourceDefinition.apiextensions.k8s.io "knativeeventings.eventing.knative.dev" is invalid: spec.validation.openAPIV3Schema.type: Required value: must not be empty at the root

@yanpzhan I've updated the description with additional details. Operator installation failure might be due to issue https://bugzilla.redhat.com/show_bug.cgi?id=1825330. Since PR related to this issue is merged we don't observe any issue with operator installation on latest CI builds.

Checked on ocp 4.5 cluster with payload: 4.5.0-0.nightly-2020-04-29-223453.

1. When 'OpenShift Serverless Operator' and 'Knative Eventing Operator' are not install, with Admin as well as basic user credentials, access from browser: https://<openshift host name>/api/console/knative-event-sources,
 it returns items with empty context: 
{"kind":"CustomResourceDefinitionList","apiVersion":"apiextensions.k8s.io/v1","metadata":{"selfLink":"/apis/apiextensions.k8s.io/v1/customresourcedefinitions","resourceVersion":"73794"},"items":[]}


2. After 'OpenShift Serverless Operator' and 'Knative Eventing Operator' are installed, with Admin as well as basic user credentials, access from browser: https://<openshift host name>/api/console/knative-event-sources,
 it returns items:

3. (Operators are installed)Try curl the api, it return nothing.
[root@MiWiFi-R1CM ~]# curl -k -H "Authorization: Bearer eAATrr-rM92wHGfobqrBOXucDCXVywhPwxL2KqNH6DE" https://console-openshift-console.apps.qe-groupd1-0430.qe.devcluster.openshift.com/api/console/knative-event-sources
[root@MiWiFi-R1CM ~]# curl -k -H "Authorization: Bearer eAATrr-rM92wHGfobqrBOXucDCXVywhPwxL2KqNH6DE" https://console-openshift-console.apps.qe-groupd1-0430.qe.devcluster.openshift.com/api/console/version
[root@MiWiFi-R1CM ~]# 

@Abhishek, thanks for you help info, from the above info, I think the api entry works from console. But curl from client get nothing, not only the /api/console/knative-event-sources, but also /api/console/version didn't return anything. Could you help to check if the client step is not correct?

@yanpzhan Try to add -v option to curl & you might see 401 Unauthorized error. If so the Bearer token used is incorrect. Try to use 'openshift-session-token' from browser & set it using -b option.

Tested again on 4.5 cluster with payload 4.5.0-0.nightly-2020-05-04-113741

Before 'OpenShift Serverless Operator' and 'Knative Eventing Operator' are installed:
