Error: Unsupported argument: An argument named "threshold" is not expected here.

[purduemike]

Used the module this way:

module "aws_anomaly_detection_alerts" { source = "StratusGrid/anomaly-detection-alerts/aws" version = "3.0.0"

cost_threshold = 1000 subscription_email = "some-email@some-email-server.com"

input_tags = local.default_tags }

Then ran terraform plan.

Expected Behavior

A successful TF plan.

Actual Behavior

Getting this error:

╷ │ Error: Unsupported argument │ │ on .terraform/modules/aws_anomaly_detection_alerts/main.tf line 17, in resource "aws_ce_anomaly_subscription" "this": │ 17: threshold = var.cost_threshold │ │ An argument named "threshold" is not expected here. ╵

Steps to Reproduce the Problem

1. Terraform plan

This solution works for me and so it should also work for you. First thing was to update main.tf to use threshold expression like this (https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/ce_anomaly_subscription):

threshold_expression { dimension { key = "ANOMALY_TOTAL_IMPACT_ABSOLUTE" values = [tostring(var.cost_threshold)] match_options = ["GREATER_THAN_OR_EQUAL"] } }

Also you need to change value to use tostring function in order to avoid the error considering set of strings. The above snippet should resolve all your problems
