CheckExistenceByID and CheckExistence always returning false with Get or GetByID confirming the resources exists

Bug Report

• Import path of package: github.com/Azure/azure-sdk-for-go/sdk/resourcemanager/resources/armresources
• SDK version: v63.4.0
• go version: go1.18.1 windows/amd64

• What happened? I created a code shown below.

// Set the package
package main

import (
	"context"
	"log"
	"testing"

	"github.com/Azure/azure-sdk-for-go/sdk/azidentity"
	"github.com/Azure/azure-sdk-for-go/sdk/resourcemanager/resources/armresources"
	"github.com/stretchr/testify/assert"
)

// Set the required variables
var subscriptionID = "82d66c37-8d61-4db4-b138-xxxxxxxxxxxx"
var apiVersion = "2022-02-01-preview"
var resourceID = "/subscriptions/82d66c37-8d61-4db4-b138-xxxxxxxxxxxx/resourceGroups/DEXT-EUN-RGRP01/providers/Microsoft.KeyVault/vaults/dexteunautomationkv01"

// Set the function to test resource existsence
func TestAzureKeyVaultExistence(t *testing.T) {
	// Create a context
	ctx := context.Background()

	// Create a new credential
	cred, err := azidentity.NewDefaultAzureCredential(nil)
	if err != nil {
		log.Fatal(err)
	}

	// Create a new resource client
	resourceClient, _ := armresources.NewClient(subscriptionID, cred, nil)

	// Check if the resource exists
	exists, err := resourceClient.CheckExistenceByID(ctx, resourceID, apiVersion, nil)
	if err != nil {
		log.Fatal(err)
	}
	assert.True(t, exists.Success)
}

• When I executed the command go test -v, I got the error shown below.

=== RUN   TestAzureKeyVaultExistence
    integration_test.go:31:
                Error Trace:    integration_test.go:31    
                Error:          Should be true
                Test:           TestAzureKeyVaultExistence
--- FAIL: TestAzureKeyVaultExistence (2.83s)
FAIL
exit status 1
FAIL    test.com        4.764s

• What did you expect or want to happen? I should have a successful output as shown in the snip below.

=== RUN   TestAzureKeyVaultExistence
--- PASS: TestAzureKeyVaultExistence (1.98s)
PASS
ok      test.com        3.437s

• How can we reproduce it?

  • Create a similar go code as above.
  • Ensure an Azure resource exists.
  • Execute the code to check the resource from the go code.

• Anything we should know about your environment. The Get-AzKeyVault command shows the resource exists as shown below

Vault Name          : dexteunautomationkv01
Resource Group Name : DEXT-EUN-RGRP01
Location            : northeurope
Resource ID         : /subscriptions/82d66c37-8d61-4db4-b138-xxxxxxxxxxxx/resourceGroups/DEXT-EUN-RGRP01/providers/Microsoft.KeyVault/vaults/dexteunautomationkv01

Changing the verb from HEAD to GET the request succeeds, but that shouldn't be necessary. @lirenhe can you please follow up with the service team about this?

Thank you for your feedback. This has been routed to the support team for assistance.

@kabal2010 Thanks for your feedback. It seems KeyVault service does not implement the HEAD operation for vaults resources. We'll involve service team to have a look. Could you please use resourceClient.GetById as a temporarily work around?

Need KeyVault team support.

@tadelesh Yes I can confirm that resourceClient.GetById works and have been using it currently, but will prefer if this can be made to work since it produces a Boolean value which I just need to check to complete my testing. Also, it's worth mentioning that this issue is not just for Azure Key Vault as I tried even a resource group and it came back with a false. It's worth the team checking this against all types of Azure resource, but I just logged this with the Key Vault resource type.
