Link to debug output

cannot provide, simple enough to test with above snippet

Panic output

No response

Expected output

Plan/apply succeeds normally and updates the comment.

Actual output

│ Error: Invalid Configuration for Read-Only Attribute
│
│ with cloudflare_list_item.item,
│ on file.tf line 54, in resource "cloudflare_list_item" "item":
│ 54: comment = "comment1"
│
│ Cannot set value for this attribute as the provider has marked it as read-only. Remove the configuration line setting the value.
│
│ Refer to the provider documentation or contact the provider developers for additional information about configurable and read-only attributes that are supported.

Steps to reproduce

1. Run TF like above

Additional factoids

The documentation is all over the place:
https://registry.terraform.io/providers/cloudflare/cloudflare/latest/docs/resources/list_item

It talks about a body {} element which is not documented in any way, nor can one use a body element:
│ Blocks of type "body" are not expected here.

If I structure the list_item resource as per the documentation:

resource "cloudflare_list_item" "item" {
  for_each = {
    "1.1.1.1" = "comment1"
    "8.8.8.8" = "comment2"
  }

  account_id = var.cloudflare_account_id
  list_id    = cloudflare_list.list.id
  
  body = [{
    ip = each.key
    comment = each.value
  }]
}

I get

│ Error: Unsupported argument
│
│   on file.tf line 54, in resource "cloudflare_list_item" "item":
│   54:   body = [{
│
│ An argument named "body" is not expected here.
