Failed to decode data of type containerd.runhcs.stats.v1.Statistics from containerd runtime

Hi, guys.
I'm doing a test which calls grpc API defined in https://github.com/containerd/containerd/blob/main/api/services/tasks/v1/tasks.proto.

I successfully call the Metrics Function using c#.

The code snippet is:

        public async Task GetMetric(string containerId)
        {
            Metadata metadata = new()
            {
                { "containerd-namespace", "k8s.io" },
            };
            var req = new MetricsRequest() { };
            req.Filters.Add("id==" + containerId);
            var resp = await this.tasksClient.MetricsAsync(req, metadata);
            Console.WriteLine($"Metric Length: {resp.Metrics.Count}");
            foreach (var metric in resp.Metrics)
            {
                Console.WriteLine($"Metrics:Container ID: {metric.Id}");
                Console.WriteLine($"Metrics:  Timestamp: {metric.Timestamp.ToDateTime():O}");
                Console.WriteLine($"Metrics: {metric.Data.TypeUrl}");
                Console.WriteLine($"Metrics: Changed proto version");
                var stats = metric.Data.Unpack<Statistics>();
                Console.WriteLine($"stats total runtime ns: {stats.Windows.Processor.TotalRuntimeNs}");
                Console.WriteLine($"stats user runtime ns: {stats.Windows.Processor.RuntimeUserNs}");
                Console.WriteLine($"stats system runtime ns: {stats.Windows.Processor.RuntimeKernelNs}");
                Console.WriteLine($"stats memory: {stats.Windows.Memory.MemoryUsagePrivateWorkingSetBytes}");
            }
        }

The log shows that metric.Data type url is:

It seems that the type is containerd.runhcs.stats.v1.Statistics.

I searched on the internet, this class definition is here:

https://github.com/microsoft/hcsshim/blob/main/cmd/containerd-shim-runhcs-v1/stats/stats.proto

Another related file referenced by stats.proto:

https://github.com/containerd/cgroups/blob/main/cgroup1/stats/metrics.proto

However, I got the error:

Exception when get metric for efdee1ad58fd765046c85dfaa018e95ea8f047e826ce923464dc43970d73e867, exception message Google.Protobuf.InvalidProtocolBufferException: Full type name for Statistics is containerd.runhcs.stats.v1.Statistics; Any message's type url is containerd.runhcs.stats.v1.Statistics
   at Google.Protobuf.WellKnownTypes.Any.Unpack[T]()
   ...

Does anyone know how to fix the issue?
