I am trying to use the azure sdk to get all the instances for a webapp running in azure. I can see in azure portal that there are 2 instances. When I run my code, it seems to get the site instance collection ok, but when the collection is enumerated, I am getting a 500 internal server error every time from azure. Does anyone have any advice on how to retrieve the list of instances for a WebSiteResource in azure?

Versions of azure sdk: "Azure.Identity" Version="1.13.2" "Azure.ResourceManager" Version="1.13.0" "Azure.ResourceManager.AppService" Version="1.3.0"

Message: Service request failed.

I am trying this:

public async Task<IEnumerable<SiteInstanceResource>> GetSiteInstances(ArmClient armClient, string resourceGroupName, string webSiteName)
{
    var subscription = await armClient.GetDefaultSubscriptionAsync();
    var resId = WebSiteResource.CreateResourceIdentifier(subscription.Data.SubscriptionId, resourceGroupName, webSiteName);
    var webSite = armClient.GetWebSiteResource(resId);
    await webSite.GetAsync();

    var siteInstances = new List<SiteInstanceResource>();
    var allSiteInst = webSite.GetSiteInstances();
    var allSites = allSiteInst.GetAllAsync();
    await foreach (var instance in allSites)
    {
        siteInstances.Add(instance);
    }
    return siteInstances;
}

I am expecting to get 2 SiteInstanceResource's that I can add to a List to pass back to the code that called this method. The code will have the ability to stop or restart a specific instance. Instead, when I await foreach on that collection, I am getting a 500 internal server error.
