Set-AzWebApp gives error Bad Request (Instead of helpful output) when encountering a webapp with

Description

We ran $webApp = Get-AzWebApp -ResourceGroupName $appServiceResourceGroupName -Name $appServiceName then Set-AzWebApp -ResourceGroupName $appServiceResourceGroupName -Name $appServiceName

And get the following output: `Set-AzWebApp : Operation returned an invalid status code 'BadRequest' At line:1 char:1

Set-AzWebApp -ResourceGroupName $appServiceResourceGroupName -Name $a ...


+ CategoryInfo          : CloseError: (:) [Set-AzWebApp], DefaultErrorResponseException
+ FullyQualifiedErrorId : Microsoft.Azure.Commands.WebApps.Cmdlets.WebApps.SetAzureWebAppCmdlet`

Expected result is that nothing would change and a warning about existing network rules would be displayed. This should NOT error out.

This should be something more helpful. Like mentioning that one of the Existing! network rules points to something that doesn't exist.
