Question 19041 in Amazon Web Sevices Question posted in
The official Amazon Web Services documentation can be found here.

Why is terraform saying that my object has no attributes? – Amazon Web Sevices

I’m using terraform 0.12.31 and trying to create some AWS SES resources. There’s one which is returning an error message:

    aws_ses_domain_identity.ses_domain_per_tenant is object with no attributes
    each.key is "a.env.account.info"

    aws_ses_domain_identity.ses_domain_per_tenant is object with no attributes
    each.key is "b.env.account.info"
    
    aws_ses_domain_identity.ses_domain_per_tenant is object with no attributes
    each.key is "c.env.account.info"

This is my code:

resource "aws_ses_domain_identity" "ses_domain_per_tenant" {
  for_each  = toset(var.enable_per_tenant_email_domain ? var.tenants_email_domain : [])
  domain    = each.key
}

resource "aws_ses_domain_dkim" "dkim_domain_per_tenant" {
  for_each  = toset(var.enable_per_tenant_email_domain ? var.tenants_email_domain : [])
  domain    = aws_ses_domain_identity.ses_domain_per_tenant[each.key].domain
}

I also have this resource as part of the same code, which is working fine:

resource "aws_route53_record" "ses_amazonses_verification_record_per_tenant" {
  for_each  = toset(var.enable_per_tenant_email_domain ? var.tenants_email_domain : [])
  records   = [aws_ses_domain_identity.ses_domain_per_tenant[each.key].verification_token]
}

Where:

tenants_email_domain = ['a.env.account.info', 'b.env.account.info', 'c.env.account.info']

What’s happening here?

    As suggested in the comments the issue is because of the variable tenants_email_domain value having single quotes '.

    On the terraform string documentation also they only mention string literals only with ".

    The following code generates a valid plan.

    
resource "aws_ses_domain_identity" "ses_domain_per_tenant" {
  for_each = toset(var.enable_per_tenant_email_domain ? var.tenants_email_domain : [])
  domain   = each.key
}

resource "aws_ses_domain_dkim" "dkim_domain_per_tenant" {
  for_each = toset(var.enable_per_tenant_email_domain ? var.tenants_email_domain : [])
  domain   = aws_ses_domain_identity.ses_domain_per_tenant[each.key].domain
}

variable "tenants_email_domain" {
  type = list(string)
  default = ["a.env.account.info", "b.env.account.info", "c.env.account.info"] ## updated ` with "" ##
}
variable "enable_per_tenant_email_domain" {
  type = bool
  default = true
}

    Except for having the way you are currently using for_each meta-argument, there is an additional thing you can do which can also help avoiding some of the errors and duplicating code and that is chaining for_each between resources [1]:

    resource "aws_ses_domain_identity" "ses_domain_per_tenant" {
  for_each = toset(var.enable_per_tenant_email_domain ? var.tenants_email_domain : [])
  domain   = each.key
}

resource "aws_ses_domain_dkim" "dkim_domain_per_tenant" {
  for_each = aws_ses_domain_identity.ses_domain_per_tenant
  domain   = each.value.domain
}

    Of course, in order for this to work, the values assigned to the tenants_email_domain have to be fixed to be strings:

    tenants_email_domain = ["a.env.account.info", "b.env.account.info", "c.env.account.info"]
