Record of reproducer

Description of problem:
Page for Deployment Config overview showed me 'e is undefined' exception, when I tried to access it, when a new pod was starting up. After some time, when the pod is started and running, Deployment Config is again available.
It's easier to reproducer on Deployment Config with "Recreate" strategy. (To see this issue with Rolling strategy I needed to have an issue in image so pod was failing)

Version-Release number of selected component (if applicable):
OpenShift Version
    4.5.0-rc.6
Kubernetes Version
    v1.18.3+6025c28

How reproducible:
Every time, with Deployment Config with Recreate strategy.

Steps to Reproduce:
1.Go to Deployment Config page and select one deployment.
2.Click on Start Rollout button.
3.After few moments the exception is displayed.

Note: It's easier to reproducer on Deployment Config with "Recreate" strategy. (To see this issue with Rolling strategy I needed to have an issue in image so pod was failing)

Actual results:
'e is undefined' exception is thrown

Expected results:
no exception

$ oc create -f dc.yaml

2. Actions -> Start Rollout, stay on DC details page and wait for some minutes, the error will appear
3. If user goes back to Workloads -> Deployment Configs -> hooks page, all tabs can be visit & displayed successfully. This error appears just after 'Start Rollout' action is performed. It will not prevent console showing DC details, so this is not a release blocker
Comment 4 ralpert 2020-07-15 18:50:55 UTC 
I tried recreating this in the web application using Yadan Pei's yaml file (needed to add namespace and update API group). I wasn't able to recreate this issue on the latest pull from master. I'll bring this up with the broader console team at scrum tomorrow to see if they have suggestions on recreating this or to confirm that this was indirectly fixed.
