Description of problem (please be detailed as possible and provide log
snippests):
--------------------------------------------------------------
Installed OCP 4.3.3 and then Installed OCS 4.2.1 subscription with Upgrade Policy "Manual". Navigated to Installed Operators->OCS Operator->Subscription Page and clicked on "1 requires Approval" under Subscription Approval->Upgrade Status (to manually approve the Install Plan)

The resulting page gave 404:Not Found Error. Attached screenshots install-1.png and install-2.png

Link giving 404 Error : https://console-openshift-console.apps.neha-rhel.qe.rh-ocs.com/k8s/ns/openshift-storage/installplans/install-7hg9m

>>Workaround:

Clicked on the same install Plan (install-7hg9m) from the Subscription->Install Plan->install-7hg9m and the Install Plan for Approval opened successfully.

Link which opens successfully: https://console-openshift-console.apps.neha-rhel.qe.rh-ocs.com/k8s/ns/openshift-storage/operators.coreos.com~v1alpha1~InstallPlan/install-7hg9m

Version of all relevant components (if applicable):
--------------------------------------------------
OCP 4.3.3

OCS = 4.2.1 (LIVE)

OS =RHEL 7.7

Does this issue impact your ability to continue to work with the product
(please explain in detail what is the user impact)?

Is there any workaround available to the best of your knowledge?

bug (1 - very simple, 5 - very complex)?

In earlier builds, we have been able to navigate to Install Plan for Approval via the "1 required approval" hyperlink.

Steps to Reproduce:

1. Install OCP 4.3.3
2. Install OCS subscription after selecting Upgrade STrategy" -> Manual
3. Goto OCS Operator->Subscription Page->Subscription Overview->Upgrade Status and click on "1 requires Approval" 
4. Check if we get 404 Error or we are taken to the Install Plan page for approval. 


Actual results:
-----------------
Clicking on "1 requires Approval"  in  "OCS Operator->Subscription Page->Subscription Overview->Upgrade Status" does not take you to the Install Plan page for approval

Expected results:
---------------------
It should take you to the Install Plan page for approval.
