It's trying to copy a sprint that doesn't exist in the source..
I want to ask if it is possible to just skip this sprint? Or is there a certain setting that says SKIP IF NODE HAVE ERROR or something like that?

All nosed MUST exist for the migration to function.

This node is has likley been deleted from the Source but still exists in the history of the work items.

You should not ever get this error if everything is working. Can you post your log file and config from that run?
