### Terraform Version ```shell 1.15.0-alpha20260304 ``` ### Terraform Configuration Files ```go func TestAccWAFV2WebACLRule_Identity_basic(t *testing.T) { ctx := acctest.Context(t) resourceName := "aws_wafv2_web_acl_rule.test" rName := acctest.RandomWithPrefix(t, acctest.ResourcePrefix) acctest.ParallelTest(ctx, t, resource.TestCase{ TerraformVersionChecks: []tfversion.TerraformVersionCheck{ tfversion.SkipBelow(tfversion.Version1_12_0), }, PreCheck: func() { acctest.PreCheck(ctx, t) }, ErrorCheck: acctest.ErrorCheck(t, names.WAFV2ServiceID), CheckDestroy: testAccCheckWebACLRuleDestroy(ctx, t), ProtoV5ProviderFactories: acctest.ProtoV5ProviderFactories, Steps: []resource.TestStep{ // Step 1: Setup { ConfigDirectory: config.StaticDirectory("testdata/WebACLRule/basic/"), ConfigVariables: config.Variables{ acctest.CtRName: config.StringVariable(rName), }, }, // Step 4: Import block with Resource Identity { ConfigDirectory: config.StaticDirectory("testdata/WebACLRule/basic/"), ConfigVariables: config.Variables{ acctest.CtRName: config.StringVariable(rName), }, ResourceName: resourceName, ImportState: true, ImportStateKind: resource.ImportBlockWithResourceIdentity, ImportPlanChecks: resource.ImportPlanChecks{ PreApply: []plancheck.PlanCheck{ plancheck.ExpectKnownValue(resourceName, tfjsonpath.New("web_acl_arn"), knownvalue.NotNull()), plancheck.ExpectKnownValue(resourceName, tfjsonpath.New(names.AttrName), knownvalue.NotNull()), plancheck.ExpectKnownValue(resourceName, tfjsonpath.New(names.AttrRegion), knownvalue.StringExact(acctest.Region())), }, }, }, }, }) } ``` ### Debug Output This seems like a regression with Terraform core because: 1. Only affects latest alpha version 2. I've tried different versions of `terraform-plugin-framework` (v1.18.0 and v1.19.0), `terraform-plugin-go` (v0.30.0 and v0.31.0), `terraform-plugin-mux` (v0.22.0 and v0.23.0), and `terraform-plugin-testing` (v1.14.0 and v1.15.0) and the result is the same. **With v1.14.7:** ```console --- PASS: TestAccWAFV2WebACLRule_Identity_basic (61.46s) PASS ok github.com/hashicorp/terraform-provider-aws/internal/service/wafv2 67.735s ``` **With v1.15.0-alpha20260218:** ```console --- PASS: TestAccWAFV2WebACLRule_Identity_basic (46.86s) PASS ok github.com/hashicorp/terraform-provider-aws/internal/service/wafv2 53.186s ``` **With v1.15.0-alpha20260304:** ```console === CONT TestAccWAFV2WebACLRule_Identity_basic web_acl_rule_identity_gen_test.go:30: removing resource aws_wafv2_web_acl_rule.test from copied state: exit status 1 Error: No value for required variable on main_gen.tf line 45: 45: variable "rName" { The root module input variable "rName" is not set, and has no default value.

Create a framework resource 2. Import it by resource identity ### Additional Context _No response_ ### References _No response_ ### Generative AI / LLM assisted development? _No response_
