Hello

Can Kasten retrieve artifact from backupPrehook  to backupPosthook?

I did use the blueprint here https://docs.kanister.io/tasks/scaleworkload.html

I did replace actions.backup line by backupPrehook 

I did replace actions.restore line by backupPosthook

(My aim: at snapshot, blueprint scales down workload as a prehook and scales up workload at posthook)

But Error running Kanister post-hook action > ActionSet Failed > Failed to render template: "backupOutput" not found

Thanks in advance!
