Bug 1910483

Created attachment 1741671 [details]
screencast of the flow depicting the issue

Description of problem:
==============================
Installed OCP 4.7 on an AWS  and installed OCS 4.7 operator on top of it. While Creating storage cluster, did the following:

1. Select Capacity and Nodes - selected the 3 nodes

2. Configure -> Clicked on Enable Encryption

 a) Added dummy entries for Connection settings -> Connect to an external key management service -> KMS Vault details. (Attached screenshot)

 b) click Next

3. In review and Create Page, 

 a) clicked on Back Button to go back to configure page. 

 b) un-clicked Enable Encryption completely. Did not un-click on "Connect to an external key management service" 

 c) Clicked Next

4. In In review and Create Page, clicked Create with Enable Encryption un-selected. 

Actual results:
===================

The Create storage cluster failed with the error message
>> Cannot read property "protocol" of null

Clicked Cancel

Expected Results
====================
Since the Encryption is now un-clicked it should not affect Storage cluster creation

Workaround:
==================
following 2 workarounds worked in creating a cluster
--------------------------------------------------
1. Clicked Cancel and in next try did not even enable encryption

2. Clicked cancel, again followed all the above steps, then came back to Configure page and un-clicked "
Connect to an external key management service" and "
Enable Encryption" both. Clicked Next and Create and Installation worked.
