IOPS is not currently working with EBS block mapping

Found a bug? Maybe our Slack Community can help.

Describe the Bug

    {
      device_name  = "/dev/sda1"
      no_device    = "false"
      virtual_name = "root"
      ebs = {
        encrypted             = true
        volume_size           = 200
        delete_on_termination = true
        iops                  = null
        kms_key_id            = null
        snapshot_id           = null
        volume_type           = "standard"
      }
    }
  ]

When you run this, you get a

│ Error: creating Auto Scaling Group (moomoo-20220804165621917300000002): ValidationError: You must use a valid fully-formed launch template. The parameter iops is not supported for standard volumes.

│

Expected Behavior

I dont know if this is supported with gp2 as well, as when i swap out "standard" for "gp2" and set iops to null, I still get the same error. If I omit the IOPS flag, this module says it is required.
