Terraform Providers AWS
1

Hi Team,
I am trying to create a cloud watch metric using the expressions and terraform, but getting Error: creating CloudWatch Metric Alarm ... ValidationError: Invalid metrics list
Below is the planned terraform code

resource "aws_cloudwatch_metric_alarm" "ec2-ebs-disk-high-avg-read-latency-alarm" {
      + actions_enabled                       = true
      + alarm_actions                         = [
          + "arn:aws:sns:us-west-1:672714205403:alarms-sns-topic",
        ]
      + alarm_description                     = "Alarm triggered when Avg read latency metric is greater than or equal to 1.5 s for a 3-minute period for webserver-new-1"
      + alarm_name                            = "ebs-disk-read-high-avg-read-latency-alarm"
      + arn                                   = (known after apply)
      + comparison_operator                   = "GreaterThanOrEqualToThreshold"
      + evaluate_low_sample_count_percentiles = (known after apply)
      + evaluation_periods                    = 1
      + id                                    = (known after apply)
      + ok_actions                            = [
          + "arn:aws:sns:us-west-1:672714205403:alarms-sns-topic",
        ]
      + tags_all                              = (known after apply)
      + threshold                             = 1500
      + treat_missing_data                    = "missing"

      + metric_query {
          + expression  = "((m1 / m2) * 1000)"
          + id          = "avg_read_latency"
          + return_data = true
        }
      + metric_query {
          + expression  = <<~EOT
                SELECT SUM(VolumeReadOps)
                FROM SCHEMA("AWS/EBS", VolumeId)
            EOT
          + id          = "m2"
          + period      = 180
          + return_data = false
        }
      + metric_query {
          + expression  = <<~EOT
                SELECT SUM(VolumeTotalWriteTime)
                FROM SCHEMA("AWS/EBS", VolumeId)
            EOT
          + id          = "m1"
          + period      = 180
          + return_data = false
        }
    }

Can you please help in figuring out the issue
