Re: Workflow Parallel task causing serialization error with Swarm Node

Can you help me understand what I'm doing wrong if this is not a bug?

What I want to achieve is to run a sh command on all swarm nodes using the parallel command.

Trying to use a nonserializable object in a local variable. Refer to the tutorial (link given).
