Empty value on self_managed_node_groups_autoscaling_group_names when default node group not created

[marpada]

Description

When creating several self-managed node groups, but NOT the default node group, the output self_managed_node_groups_autoscaling_group_names contains an empty value.

self_managed_node_groups_autoscaling_group_names = [
  "bottlerocket-self-mng-2022080805253047320000002e",
  "complete-self-mng",
  "",
  "efa-20220808052530474100000030",
  "mixed-20220808052530475200000031",
]

Reproduction Code [Required]

Use self-managed group example, but disable the creation of the default node group:

  self_managed_node_groups = {
    default_node_group = { create = false }
    ....
    }

Steps to reproduce the behavior:

Expected behavior

output.self_managed_node_groups_autoscaling_group_names should only contain valid values

self_managed_node_groups_autoscaling_group_names = [
  "bottlerocket-self-mng-2022080805253047320000002e",
  "complete-self-mng",
  "efa-20220808052530474100000030",
  "mixed-20220808052530475200000031",
]

Actual behavior

output.self_managed_node_groups_autoscaling_group_names includes an empty value.

self_managed_node_groups_autoscaling_group_names = [
  "bottlerocket-self-mng-2022080805253047320000002e",
  "complete-self-mng",
  "",
  "efa-20220808052530474100000030",
  "mixed-20220808052530475200000031",
]

Additional context

This issue prevents from using output.self_managed_node_groups_autoscaling_group_names for creating other resources based on autoscaling names. Sometimes the generated list can be filtered out but this not always works, for instance if needed to use it in a count or for_each parameter as Terraform cannot determine the content during the plan.
