here's my part of my code that I am having issues with. Unfortunately I could not understand the relationship between the last answer, despite being almost what I need, and my situation.

data "aws_internet_gateway" "zyz_igw" {
  depends_on = [aws_internet_gateway.this]

    filter {
    name   = "attachment.vpc-id"
    values = aws_vpc.this[count.index]
    #values = [aws_vpc.this[count.index]]   #based on https://www.terraform.io/docs/providers/oci/guides/filters.html
  }

  filter {
    name   = "tag:Name"
    values = ["ZYZ_Mirror_ZYZ-tp-zyz-IGW"]
  }
}

The error I am getting is the following:

Error: Reference to "count" in non-counted context

  on modules/xyz/main.tf line 292, in data "aws_internet_gateway" "zyz_igw":
 292:     values = aws_vpc.this[count.index]

The "count" object can be used only in "resource" and "data" blocks, and only
when the "count" argument is set.

I get confused since I believe my issue may be with the resource and not sure how to change the data. I also saw something related to 'for_each' to use that instead of 'count' on 0.12. But the in the very beginning of my code I have the normal 'aws_vpc' resource:

resource "aws_vpc" "this" {
  count = var.zyz_create_vpc ? 1 : 0

As far as your error goes.... count is a reserved name. It's only accessible when the block you're writing has a count set!

You just need to specify the count of aws_internet_gateway data resources you're trying to get. Your code implies there is more than one.

data "aws_internet_gateway" "zyz_igw" {
   count = 1000000000
   ...

  • Thanks @thisguy123, I am in fact new. I have made a mention about another question when I was trying to get an answer there. Then I read I could not ask onto a question and forgot to add the link: devops.stackexchange.com/questions/8937/….

  • I did what you suggested and got several other errors: ``` Error: Reference to undeclared resource on modules/tp-chi/main.tf line 274, in resource "aws_default_route_table" "this": 274: default_route_table_id = aws_vpc.this[index.count].default_route_table_id A managed resource "index" "count" has not been declared in tp-chi. ```

  • AND Error: Missing resource instance key on modules/tp-chi/main.tf line 279, in resource "aws_default_route_table" "this": 279: gateway_id = data.aws_internet_gateway.tp-chi_igw.id Because data.aws_internet_gateway.tp-chi_igw has "count" set, its attributes must be accessed on specific instances. For example, to correlate with indices of a referring resource, use: data.aws_internet_gateway.tp-chi_igw[count.index]
