[BUG] `cloudfoundry_org` resource rejects empty labels map (`{}`)

[geigerj0]

Describe the bug

The provider rejects an empty labels map ({}) with the following error:

│ Error: Invalid Attribute Value
│ 
│   with cloudfoundry_org.my_org,
│   on main.tf line 18, in resource "cloudfoundry_org" "my_org":
│   18:   labels = var.cf_org_labels
│ 
│ Attribute labels map must contain at least 1 elements, got: 0

Expected Behavior

Setting labels = {} (an empty map) on a cloudfoundry_org resource should be valid. An organization may intentionally have no labels provided via a variable. The provider should accept an empty map and either skip label management or remove any existing labels.

Steps To Reproduce

variable "cf_org_labels" {
  type = map(string)
}

resource "cloudfoundry_org" "my_org" {
  name   = "my-org"
  labels = var.cf_org_labels
}

terraform apply -var='cf_org_labels={}'

What version of the Terraform provider are you using?

1.13.0

What version of the Terraform CLI are you using?

1.14.0

What CF API version are you using?

3.216.0

Hi @geigerj0 ,
Is there a specific reason for setting labels to an empty map?

If the labels attribute is omitted from the Terraform configuration, no labels will be applied to the organization anyway. Setting it explicitly to an empty map doesn’t change the behavior, so I’m wondering if there’s a particular use case behind this approach?

[geigerj0]

One use case would be the following

• organization labels need to be configurable via a variable like var.cf_org_labels
• in case someone decides to not configure any labels, var.cf_org_labels is set to {}

I just found out that labels = null is working but labels = {} not 🤷‍♂️

Hi @geigerj0,
At this time, we have decided not to allow empty labels, as doing so would impact other resources and introduce breaking changes. If a default value is required for a label, it can be explicitly set to null within the HCL configuration. We will include an example demonstrating this approach in the documentation for clarity.
