We can ignore pre-staging failure as we dont yet have a means of testing assistant stuff on pre-staging (issue has been raised for that here: https://github.com/FlowFuse/CloudProject/issues/475)

(though @ppawlowski might want to take a look at why that step failed?)

It failed due to the lack of resources on the cluster.
