Rancher Error when browsing clusters and refreshing

[gaktive]

Internal reference: SURE-3907
Reported in 2.6.3

A user is seeing an issue with the new Interface where when browsing to a cluster and hitting refresh the Default backend error screen will appear.

It is triggered by, clicking into a cluster, then hitting F5. usually the first time,

What's likely missing is the schema for that type in the body of the response for the request to /k8s/clusters/(id)/v1/schemas

Attached are some screenshots.

@nwmac has been able to repro but it's a tight window to capture it as the cluster comes up. It may take time to troubleshoot though since there's a lot of tear down required, but we need to handle this race condition with something to display and then a retry.

@gaktive I tried again to reproduce and could not - previously I could deploy the docker AIO image and if I quickly logged in and tried to explore the cluster, I got the fail-whale page.

• Refreshed webpage after cluster creation, after scaling down/up nodes.
• This error is not seen
• Tried multiple times.
• Will close the issue now. Will lo a new one if this is seen again.
