When running a checkup (via the UI), clicking on the checkup in the Checkups page leads to a blank page.

CNV 4.15.0
OCP 4.15.0-rc.5

* The NodeNetworkConfigurationPolicy and NetworkAttachmentDefinition in the first 2 steps can probably be created via the UI as well, but I created them manually.

1.
Create a linux bridge interface using a valid NodeNetworkConfigurationPolicy:
$ oc apply -f nncp-linux-bridge.yaml 
nodenetworkconfigurationpolicy.nmstate.io/node-linux-bridge created

(Change the relevant parameters, e.g. port name, according to your cluster).

2.
Create a NetworkAttachmentDefinition:
$ oc apply -f linux-bridge-nad.yaml 
networkattachmentdefinition.k8s.cni.cncf.io/lnx-br-nad created

3.
In the UI - go to Virtualiztion -> Checkups

4.
Press "Run checkup" button (in the middle of the screen).

5.
From the NetworkAttachmentDefinition drop-down - select the one you created.
Leave all the other parameters as they are, and press "Run" button.

6.
Wait for the checkup to finish. If it's a valid checkup then it should finish after its default 5 seconds duration; if it's invalid (for example - if some parameter in the NetworkAttachmentDefinition is wrong) then the checkup will finish after its default 5 minutes timeout.

7.
Press the checkup's link in the Checkups page.

<BUG>
Blank page (see attached image).

Some info.
I don;t know what the design is, but I would expect to see something.
IMHO it should prsent the checkup's comfigmap, which includes all the setup info and the result summary,

Same result when the checkup ends successfully or fails.
