I'm trying to create EKS on my AWS account, and getting an error "Call to function "coalescelist" failed: no non-null arguments." Here comes the details. I have been searching the same or similar issues, but have not found any workarounds - if someone gave me specific workarounds of this, that would be appreciated.
