Issue with acceptance tests for customer provider

Hey folks,

I’m trying to implement a custom Terraform provider for Bitwarden and following the tutorial with the Terraform Plugin Framework.

Manually I’ve verified my implementation is working as expected. But when implementing the acceptance tests, I need some help.

The last_updated field during a Read & Update TestStep is failing with the following message:

  | exit status 1
  | There are some problems with the CLI configuration:
  | ╷
  | │ Error: Invalid provider installation dev overrides
  | │
  | │ The entry "onesignal/terraform-provider-bitwarden" in 1:1 is not a valid
  | │ provider source string.
  | ╵
  | As a result of the above problems, Terraform may not behave as intended.
  | Error: Provider produced inconsistent result after apply
  | When applying changes to bitwarden_group.test, provider
  | "provider[\"\"]" produced an
  | unexpected new value: .last_updated: was cty.StringVal("Friday, 04-Aug-23
  | 16:23:02 CEST"), but now cty.StringVal("Friday, 04-Aug-23 16:23:07 CEST").
  | This is a bug in the provider, which should be reported in the provider's own
  | issue tracker.

The last_updated field is set during the initial creation and later updated during the update step with a new value. I expect it to change.

Currently, my test case looks as follows:

func TestAccGroupResource(t *testing.T) {
	resource.Test(t, resource.TestCase{
		PreCheck:                 func() { testAccPreCheck(t) },
		ProtoV6ProviderFactories: testAccProtoV6ProviderFactories,
		Steps: []resource.TestStep{
			// Create and Read testing
				Config: testAccGroupResourceConfig("one", "", true),
				Check: resource.ComposeAggregateTestCheckFunc(
					resource.TestCheckResourceAttr("bitwarden_group.test", "name", "one"),
					resource.TestCheckResourceAttr("bitwarden_group.test", "access_all", "true"),
					resource.TestCheckResourceAttrSet("bitwarden_group.test", "id"),
					resource.TestCheckResourceAttrSet("bitwarden_group.test", "last_updated"),
			// ImportState testing
				ResourceName:      "bitwarden_group.test",
				ImportState:       true,
				ImportStateVerify: true,
				// This is not normally necessary, but is here because this
				// example code does not have an actual upstream service.
				// Once the Read method is able to refresh information from
				// the upstream service, this can be removed.
				ImportStateVerifyIgnore: []string{"last_updated"},
			//Update and Read testing
				Config: testAccGroupResourceConfig("two", "external-two", false),
				Check: resource.ComposeAggregateTestCheckFunc(
					resource.TestCheckResourceAttr("bitwarden_group.test", "name", "two"),
					resource.TestCheckResourceAttr("bitwarden_group.test", "external_id", "external-two"),
					resource.TestCheckResourceAttr("bitwarden_group.test", "access_all", "false"),
			// Delete testing automatically occurs in TestCase

When I verify with the tutorial repository is following the same pattern, also updating the last_updated timestamp during the update action, but I assume it’s not failing the tests.

If there’s anyone who could point me in the right direction, I’d appreciate it :pray:
