cloudflare_access_policy: When using multiple saml blocks in an include block, only the last one is saved

[bobthebuilderberlin]

Confirmation

• My issue isn't already found on the issue tracker.
• I have replicated my issue using the latest version of the provider and it is still present.

Terraform and Cloudflare provider version

Terraform v1.0.11
cloudflare provider version = "3.27.0"

Affected resource(s)

cloudflare_access_policy

Terraform configuration files

resource "cloudflare_access_policy" "my-application" {
  application_id = <application-id>
  account_id     = local.cloudflare_account_id
  name           = "allow-saml"
  precedence     = "3"
  decision       = "allow"

  include {
    dynamic "saml" {
      for_each = toset(["group-1", "group-2"])
      content {
        attribute_name  = "Groups"
        attribute_value = saml.key
      }
    }
  }
}

Expected output

After an apply, not only the last item of the saml block list should be saved, but all of the items.
Providing multiple include blocks with single saml blocks does not help.

Actual output

plan output after a singular apply:

  ~ resource "cloudflare_access_policy" "my-policy" {
        id             = "<id>"
        name           = "allow-saml"
        # (4 unchanged attributes hidden)

      ~ include {
            # (11 unchanged attributes hidden)

          ~ saml {
              ~ attribute_value = "group-2" -> "group-1"
                # (1 unchanged attribute hidden)
            }
          + saml {
              + attribute_name  = "Groups"
              + attribute_value = "group-2"
            }
        }
    }

Same in the UI, only the last element is saved.

Steps to reproduce

1. Create multiple saml blocks in the include block of a cloudflare_access_policy resource
2. terraform apply
3. terraform plan shows that only the first element is saved.
