### Terraform Version ```shell Terraform v1.11.3 on linux_amd64 + provider registry.terraform.io/hashicorp/azurerm v4.25.0 ``` ### Terraform Configuration Files ```terraform terraform { required_providers { azurerm = { source = "hashicorp/azurerm" version = "~> 4" } } } provider "azurerm" { features {} subscription_id = "TEST_SUBSCRIPTION_ID" } variable "acr_ip_allowlist" { type = map(string) default = { "Office" = "1.2.3.4" } } resource "azurerm_container_registry" "shared" { name = "test" resource_group_name = "test-rg" location = "canadaeast" sku = "Premium" public_network_access_enabled = false network_rule_set { default_action = "Deny" dynamic "ip_rule" { for_each = var.acr_ip_allowlist content { action = "Allow" ip_range = "${ip_rule.value}/32" } } } } ``` ### Debug Output https://gist.github.com/oliver-simwell/60abc7b9e06f9b60ae80493081e7fe79 ### Expected Behavior Should work ### Actual Behavior Error: Unknown variable │ │ on main.tf line 20, in resource "azurerm_container_registry" "acr": │ 20: for_each = var.acr_ip_allowlist │ │ There is no variable named "var". ### Steps to Reproduce 1. terraform init 2. terraform plan: see error However if you now replace the `var.acr_ip_allowlist` by the default value, like this: ``` # for_each = var.acr_ip_allowlist for_each = { "Office" = "1.2.3.4" } ``` and repeat the plan: no error ### Additional Context _No response_ ### References - #35679 ### Generative AI / LLM assisted development? I asked a couple of LLMs about the error, the solutions were as non-sensical as the error.
