Confirmation

• This is a bug with an existing resource and is not a feature request or enhancement. Feature requests should be submitted with Cloudflare Support or your account team.
• I have searched the issue tracker and my issue isn't already found.
• I have replicated my issue using the latest version of the provider and it is still present.

Terraform and Cloudflare provider version

Terraform v1.8.2
(Although it has nothing to do with the issue)

Affected resource(s)

cloudflare_certificate_pack

Terraform configuration files

resource "cloudflare_certificate_pack" "certificate" {
  zone_id                = data.cloudflare_zone.zone.id
  type                   = "advanced"
  hosts                  = ["b.example.com", "a.example.com", "c.example.com"]
  validation_method      = "txt"
  validity_days          = 90
  certificate_authority  = "lets_encrypt"
  cloudflare_branding    = false
  wait_for_active_status = true
}

Panic output

No response

Expected output

In the created certificate pack the order of hostnames should be retained. This can be checked on cloudflare' API:
https://api.cloudflare.com/client/v4/zones/{zone_id}/ssl/certificate_packs/{certificate_pack_id} (https://developers.cloudflare.com/api/operations/certificate-packs-get-certificate-pack)

Actual output

The order of hostnames in the created certificate pack is not defined.

Steps to reproduce

See "Additional factoids"

Additional factoids

The type of the hosts attribute for the cloudflare_certificate_pack resource is wrong:
On the Cloudflare's API it is defined as an array[strings] (see: https://developers.cloudflare.com/api/operations/certificate-packs-order-advanced-certificate-manager-certificate-pack#request-body), on the other hand this resource defines it as set(string) (see: https://registry.terraform.io/providers/cloudflare/cloudflare/latest/docs/resources/certificate_pack#hosts )
This will make the order of the hostnames passed to the Cloudflare's API undefined, so the user has no control over that. This is however important, because Cloudflare will use the first entry for the CN of the certificate.

Currently the only workaround is to create the Advanced certificate pack manually, although the UI will also sort the hostnames in a certain order after the pack is created, but for creating the certificate the order of the provided hostnames are respected.
