**Describe the bug**

There appears to be a race condition e.g. in the time between creating an app and then creating a secret for it or granting permissions to it, Resulting in flaky behaviour where usually the granting of permissions or secret creation will succeed but occasionally it will give errors such as:

* ERROR: Resource '' does not exist or one of its queried reference-property objects are not present.
* OR
* ERROR: Resource 'xxxxxxx-xxxxx-xxxx-xxxx-xxxxxxxxxx' does not exist or one of its queried reference-property objects are not present.

**To Reproduce**
Powershell script that shows this behaviour where roughly 25% of the runs fail.

```
#region "required parameters"
$PermissionAppName = "app"
$PermissionClientSecretName = "appsecret"
$tenantName = "tenantname"
#endregion

#region "race condition"
$PermissionClientInfo = (az ad app create --display-name $PermissionAppName --sign-in-audience AzureADMyOrg --only-show-errors) | ConvertFrom-Json
$PermissionClientID = $PermissionClientInfo.appId
$PermissionClientSecretDuration = 1
$PermissionClientSecret = (az ad app credential reset --id $PermissionClientID --append --display-name $PermissionClientSecretName --years $PermissionClientSecretDuration --query password --output tsv --only-show-errors)
#endregion

Write-Color "green" "Client ID for $PermissionAppName`: $PermissionClientID"
Write-Color "green" "Please take a moment to make a note of and protect the following client secret; as you will not be able to access it again."
Write-Color "green" "Client secret for $PermissionAppName`: $PermissionClientSecret"
```

**Expected behavior**

Secret value should be written to console, happens most of the time.

But some of the time, secret value will be empty due to suspected race condition, and will output to the console the errors listed above.
