Description of problem (please be detailed as possible and provide log
snippets):

If there is a syntax error in the csi-kms-connection-details configmap, for eg: a missing comma as shown below, 

$ oc get cm csi-kms-connection-details -n openshift-storage -o yaml
apiVersion: v1
data:
  vault-tenant-sa-auth: |-
    {
      "encryptionKMSType": "vaulttenantsa",
      "vaultAddress": "https://vault.ocs.com:8200",
      "vaultBackendPath": "test-sa"
      "vaultCAVerify": "false"
    }

in the storage class creation page, on clicking the "Enable Encryption" checkbox the whole screen goes blank. This could be because the UI is unable to parse the configmap to populate the KMS connection details section in the UI.
