cloudflare_list purges if no IP is being added

[lifeofguenter]

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

Applying the following:

Terraform will perform the following actions:

  # cloudflare_list.known_ip will be updated in-place
  ~ resource "cloudflare_list" "known_ip" {
        id         = "123"
        name       = "known_ip"
        # (2 unchanged attributes hidden)
    }

  # cloudflare_list.office_ip will be updated in-place
  ~ resource "cloudflare_list" "office_ip" {
        id         = "abc"
        name       = "office_ip"
        # (2 unchanged attributes hidden)
    }

Plan: 0 to add, 2 to change, 0 to destroy.

will actually purge all cloudflare_list_item - evne though not indicated by the plan output

Affected resource(s)

• cloudflare_list
• cloudflare_list_item

Terraform configuration files

resource "cloudflare_list" "known_ip" {
  account_id = "abc"
  name       = "known_ip"
  kind       = "ip"
}

locals {
  natgw_ips = [
    for ip in module.network.natgw_ips : split("/", ip)[0]
  ]

  known_ips = compact(concat([
    # https://docs.sentry.io/security-legal-pii/security/ip-ranges/
    "34.141.31.19",         # sentry.io EU
    "34.141.4.162",         # sentry.io EU
    "35.234.78.236",        # sentry.io EU
  ], local.natgw_ips))
}

resource "cloudflare_list_item" "known_ips" {
  for_each   = toset(local.known_ips)
  account_id = cloudflare_list.known_ip.account_id
  list_id    = cloudflare_list.known_ip.id
  comment    = "Known IP"
  ip         = each.value

Thank you for reporting this issue! For maintainers to dig into issues it is required that all issues include the entirety of TF_LOG=DEBUG output to be provided. The only parts that should be redacted are your user credentials in the X-Auth-Key, X-Auth-Email and Authorization HTTP headers. Details such as zone or account identifiers are not considered sensitive but can be redacted if you are very cautious. This log file provides additional context from Terraform, the provider and the Cloudflare API that helps in debugging issues. Without it, maintainers are very limited in what they can do and may hamper diagnosis efforts.

This issue has been marked with triage/needs-information and is unlikely to receive maintainer attention until the log file is provided making this a complete bug report.

Thank you for opening this issue and sorry to hear you're hitting issues. Unfortunately, the reproduction case provided contains HCL dynamic expressions. Examples of these are:

• Conditionals
• For loops
• Dynamic blocks
• Modules and module references

Maintainers don't accept these as reproduction cases since using these constructs and expressions can hold their own logic bugs which are outside of the provider and not able to be diagnosed.

For maintainers to triage this issue, we recommend providing a minimal reproduction test case that is only contains the impacted resources and can be easily reproduced in an isolated environment. Without providing this, maintainers are limited in what support they can provide.
