Terraform Configuration Files

resource "oci_core_public_ip" "myip" {
  compartment_id = var.compartment_id
  lifetime       = "RESERVED"

  defined_tags = var.defined_tags # <--- we're changing this map
}

resource "oci_core_nat_gateway" "mynat" {
  compartment_id = var.compartment_id
  vcn_id         = var.vcn_id

  public_ip_id = oci_core_public_ip.myip.id
}

Debug Output

None needed, plan goes through as one would expect:

  # oci_core_public_ip.myip will be updated in-place
  ~ resource "oci_core_public_ip" "myip" {
      ~ defined_tags         = {
           [REDACTED]
        }
        id                   = "[REDACTED]"
        # (10 unchanged attributes hidden)
    }

Panic Output

None happens.

Expected Behavior

Apply goes through.

Actual Behavior

Apply doesn't go through, errors with:
Error: 404-NotAuthorizedOrNotFound, Cannot update public IP assigned to an entity of type NAT_GATEWAY
but I'm just changing the tags, I should be allowed to do this.

2. terraform apply
3. Edit the tags map
4. terraform apply

Important Factoids

None.
