Acceptance test import verification fails with Terraform 1.14.3 (ImportStateVerify): “Failed state verification, resource with ID … not found”

Module version

# go list -m github.com/hashicorp/terraform-plugin-sdk/v2

Relevant provider source code

We run an acceptance test that creates a resource, then performs terraform import via ImportState with verification enabled. This worked with Terraform v1.2.9, but fails with Terraform v1.14.3 during the import verification step.

func TestAccNutanixSubnet_basic(t *testing.T) {
	r := randIntBetween(31, 40)
	subnetName := fmt.Sprintf("acctest-managed-%d", r)

	resource.Test(t, resource.TestCase{
		PreCheck:     func() { acc.TestAccPreCheck(t) },
		Providers:    acc.TestAccProviders,
		CheckDestroy: testAccCheckNutanixSubnetDestroy,
		Steps: []resource.TestStep{
			{
				Config: testAccNutanixSubnetConfig(r),
				Check: resource.ComposeTestCheckFunc(
					testAccCheckNutanixSubnetExists(resourceNameSubnet),
					resource.TestCheckResourceAttr(resourceNameSubnet, "name", subnetName),
					resource.TestCheckResourceAttr(resourceNameSubnet, "description", "Description of my unit test VLAN"),
				),
			},
			{
				ResourceName:            resourceNameSubnet,
				ImportState:             true,
				ImportStateVerify:       true,
				ImportStateVerifyIgnore: []string{"description"},
			},
		},
	})
}

Terraform Configuration Files

func testAccNutanixSubnetConfig(r int) string {
	return fmt.Sprintf(`
data "nutanix_clusters" "clusters" {}

locals {
	cluster1 = [
	for cluster in data.nutanix_clusters.clusters.entities :

resource "nutanix_subnet" "acctest-managed" {

}
`, r)
}

Expected Behavior

ImportStateVerify should successfully import the resource and verify state (same behavior as with Terraform v1.2.9).

Actual Behavior

With Terraform v1.14.3, the import verification step fails:

Failed state verification, resource with ID terraform-202601061429166713000000c0 not found

The create step succeeds; the failure happens in step 2 (import + verification).

Steps to Reproduce

1. Ensure Terraform v1.14.3 is installed/active (e.g., via tfenv) and confirm with terraform version.
2. Run the acceptance test with TF_ACC enabled:
   • TF_ACC=1 go test ./... -run TestAccNutanixSubnet_basic -v
3. Observe failure during the import verification step.
4. Switch to Terraform v1.2.9 and rerun the same command.
5. Observe the test passes with Terraform v1.2.9.

Environment

• OS: Linux (WSL2) (linux 5.15.150.1-microsoft-standard-WSL2)
• Terraform: v1.2.9 (pass) vs v1.14.3 (fail)
• Go: go1.25.3 linux/amd64
