[BUG] Create Managed Certificate failed with status code 202

Library name and version

Azure.ResourceManager.AppService 1.2.0

Describe the bug

I use below code to create a managed certificate but I encounter error

2024-10-27T22:23:57Z   [Error]   Failed to create managed cert
2024-10-27T22:23:57Z   [Error]   Service request failed.
Status: 202 (Accepted)

Service request succeeded. Response content and headers are not included to avoid logging sensitive data.
2024-10-27T22:23:57Z   [Error]      at Azure.ResourceManager.AppService.CertificatesRestOperations.CreateOrUpdateAsync(String subscriptionId, String resourceGroupName, String name, AppCertificateData data, CancellationToken cancellationToken)
   at Azure.ResourceManager.AppService.AppCertificateCollection.CreateOrUpdateAsync(WaitUntil waitUntil, String name, AppCertificateData data, CancellationToken cancellationToken)

The code is

            ResourceGroupResource resourceGroupResource =
                this.client.GetDtmbResourceGroupResource(stamp.ManagedSubscriptionId, stamp.ResourceGroupName);
            AppCertificateCollection collection = resourceGroupResource.GetAppCertificates();

            string name = $"{req.DtsEnvName}-cert";
            string hostName = req.DomainName;
            //DomainNameGenerator.GenerateDomainName(req.DtsEnvName, req.Location, this.dnsConfig.DnsZoneName);
            AppCertificateData data = new(new AzureLocation(req.Location))
            {
                // HostNames = { hostName },
                CanonicalName = hostName, 
                ServerFarmId = new ResourceIdentifier(req.AspResourceId),
            };

            ArmOperation<AppCertificateResource> lro =
                await collection.CreateOrUpdateAsync(WaitUntil.Completed, name, data);
            AppCertificateResource result = lro.Value;
            AppCertificateData resourceData = result.Data;

Noticed the error code is 202, I don't really see what this error happen as it's supposed to be a long running/async operation, I am using

            ArmOperation<AppCertificateResource> lro =
                await collection.CreateOrUpdateAsync(WaitUntil.Completed, name, data);

with WaitUntil.Completed set, it should wait till the long running operation finished, but it's not.

Later I checked on the azure portal, I saw that the cert was created successfully. So I don't know why my code gives error, it should await and return succeed.

Expected behavior

The code should work synchronously to create a managed certificate.

Actual behavior

Gives error

2024-10-27T22:23:57Z   [Error]   Failed to create managed cert

Reproduction Steps

try out below code

            ResourceGroupResource resourceGroupResource =
                this.client.GetDtmbResourceGroupResource(stamp.ManagedSubscriptionId, stamp.ResourceGroupName);
            AppCertificateCollection collection = resourceGroupResource.GetAppCertificates();

            string name = $"{req.DtsEnvName}-cert";
            string hostName = req.DomainName;
            //DomainNameGenerator.GenerateDomainName(req.DtsEnvName, req.Location, this.dnsConfig.DnsZoneName);
            AppCertificateData data = new(new AzureLocation(req.Location))
            {
                // HostNames = { hostName },
                CanonicalName = hostName, 
                ServerFarmId = new ResourceIdentifier(req.AspResourceId),
            };

            ArmOperation<AppCertificateResource> lro =
                await collection.CreateOrUpdateAsync(WaitUntil.Completed, name, data);
            AppCertificateResource result = lro.Value;
            AppCertificateData resourceData = result.Data;
