Use var in a dynamic block in a module

Terraform
1

Hi there, I’m trying to write a module that accepts an object as a variable, however when I try to reference that variable in a dynamic block, terraform validate says that “var” isn’t defined…

resource "azurerm_frontdoor_firewall_policy" "fd_waf_policy" {
    name = var.name
    resource_group_name = var.resource_group_name
    location = var.location

    dynamic "custom_rule" {
        for_each = var.policy
        content {
          ...
        }
    }
}

The error is this:

│ Error: Unknown variable
│
│ on modules\fd-waf\main.tf line 11, in resource “azurerm_frontdoor_firewall_policy” “fd_waf_policy”:
│ 11: for_each = var.policy
│
│ There is no variable named “var”.

I’m using TF 1.2.1 on Windows

There is no var. here - either the Terraform error message is incorrectly quoting your code (seems unlikely?), or your code isn’t actually the same as the code you posted in the code block in your post!

Yup I pasted the wrong output… I will edit original

Did you ever resolve this issue?
I am having a similar issue with dynamic blocks.

@roy.madden,

Please start a new topic and share the details of your problem. You’re more likely to get a useful answer if you describe exactly the problem you have, rather than just asserting that it seems similar to some other problem.
