Terraform Configuration Files

locals {
  object_items = [
    {
      a = "1"
      b = "2"
    },
    {
      a = "3"
      b = "4"
    }
  ]
  as_map = {
    for item in local.object_items : "key-${item.a}" => "value-${item.b}"  # <-- errors here
  }
  as_list = [
    for item in local.object_items : "just-${item.a}"  # <-- error here
  ]

  list_items = [["a"], ["b"], ["c"]]
  as_list2 = [
    for item in local.list_items : "text-${item[0]}"  # <-- error here
  ]
}

Expected Behavior

All of this code should be accepted as valid (Terraform itself is happy with it)

Actual Behavior

The interpolations in the strings are marked as errors, specifically Unknown resource type on the item tokens and Unresolved reference a/b on the a/b attributes.

When these attributes (or indices) are accessed directly (without being in a string interpolation), no errors are shown, it all works fine.

Steps to Reproduce

1. Paste the above snippet into a .tf file (not a scratch file - for some reason the errors are not reported there)
2. Observe the errors
