Hi,
That seems to be the case. Is there a way that I can put an object in some
global place where all the workers can access it?
Doing the following at the start (before I make multiple workers) does not work:
Assign('global.control', control, globalenv())
Thanks for your help!
Kind regards,
Greg

Perhaps you forgot to populate the object to the client nodes?
Hard to say without any reproducible example code.
