Scale Deployment to Zero Policy issue

[VegardEikenes]

I have tried to implement this policy in my cluster:
https://kyverno.io/policies/other/scale-deployment-zero/scale-deployment-zero/

It seems to work just fine when the restarting pod has 1 container. However, if the restarting pod has more than 1 container, i get this error:

ERR github.com/kyverno/kyverno/pkg/background/mutate/mutate.go:180 > error="failed to mutate existing resource, rule annotate-deployment-rule, response error: failed to evaluate preconditions: failed to substitute variables in condition key: failed to resolve sum(request.object.status.containerStatuses[*].restartCount || [0]) at path : JMESPath query failed: JMESPath function 'sum': invalid operand"

The policy should be adapted to work with more than just 1 container, and sum the restartcount of every container.
