Terraform aws_cloudwatch_metric_alarm An error occurred contacting the server

Question

I'm creating CloudWatch alarm with Terraform, e.g.:

resource "aws_cloudwatch_metric_alarm" "terraform_cloudwatch_metric_alarm_CPUUtilization" {
alarm_name = "terraform_cloudwatch_metric_alarm_CPUUtilization"
alarm_description = "terraform_cloudwatch_metric_alarm_CPUUtilization"
comparison_operator = "GreaterThanOrEqualToThreshold"
evaluation_periods = "1"
metric_name = "CPUUtilization"
namespace = "AWS/EC2"
period = "300"
statistic = "Average"
threshold = "90"
dimensions = {
    "Instance­Id" = "${aws_instance.terraform_instance.id}"
}

}

But I'm getting An error occurred contacting the server:

When I'm creating the same from console it works fine:

Any ideas why and how to fix it?

PS Temporary workaround is to add local-exec to aws_instance: provisioner "local-exec" { command = <<-EOF aws cloudwatch put-metric-alarm \ --alarm-name "cloudwatch_metric_alarm_CPUUtilization" \ --alarm-description "cloudwatch_metric_alarm_CPUUtilization" \ --no-actions-enabled \ --metric-name "CPUUtilization" \ --namespace "AWS/EC2" \ --statistic "Average" \ --dimensions "Name=InstanceId,Value=${aws_instance.terraform_instance.id}" \ --period "300" \ --unit "Percent" \ --evaluation-periods "1" \ --threshold "90" \ --comparison-operator "GreaterThanOrEqualToThreshold" \ --treat-missing-data "missing" EOF }

The problem was in SOFT HYPHEN present in dimension name, both VSCode and Sublime 3 showed code normally:

only Vim/nano were showing correctly:
