[BUG]: github_issue_label causes provider panic (nil pointer dereference) during apply

[davewebhost]

Expected Behavior

The github_issue_label resource should create or update the specified label successfully, or return a handled API error if the request fails.

Actual Behavior

terraform apply causes the GitHub provider to panic with a nil pointer dereference during creation of a github_issue_label resource. Terraform reports that the provider plugin crashed.

Full panic stack trace included below.

Terraform Version

Terraform v1.14.2

Affected Resource(s)

github_issue_label

Terraform Configuration Files

provider "github" {
  owner = "REDACTED_OWNER"
}
resource "github_issue_label" "terraform_managed" {
  repository  = "REDACTED_REPO"
  name        = "terraform-managed"
  color       = "5319e7"
  description = "Managed by Terraform"
}

Steps to Reproduce

1. Configure the GitHub provider with a valid owner and authentication via GITHUB_TOKEN.
2. Add a github_issue_label resource as shown in the configuration above.
3. Run terraform init.
4. Run terraform plan (plan succeeds).
5. Run terraform apply.
6. Provider crashes during label creation with a nil pointer dereference.
