Grpc Error in `dotnet-isolated` in net7 and docker

I have two functions, one is a CronTrigger, which appears to be working fine the other is an OrchestrationTrigger function. This is running in dotnet-isolated, net7, in docker.

I can see in my logs that the cron is launching, it also successfully schedules the other function, i can see the instanceId in the logs.

The line where I call WaitForInstanceCompletionAsync(instanceId, ...) is where it throws an exception. Here are the details:

{
    "created": "@1671260404.629909577",
    "description": "Error received from peer ipv4:127.0.0.1:4001",

    "file_line": 1070,
    "grpc_message": "Exception was thrown by handler.",
    "grpc_status": 2
}

I’m not sure how this can happen. This is running in a pod, which has both processes…

Example code

using System.Threading;
using Microsoft.Azure.Functions.Worker;
using Microsoft.DurableTask;

namespace Recovery.Functions;

public class HelloExample
{
  private readonly ILogger logger;

  public HelloExample(ILogger<HelloExample> logger) => this.logger = logger;

  [Function(nameof(HelloExample))]
  public async Task<string> Hello([OrchestrationTrigger] TaskOrchestrationContext context, string name)
  {
    var instanceId = context.InstanceId;
    this.logger.LogInformation("Hello Workflow Running: {name} ({instanceId})", name, instanceId);

    return await Task.FromResult($"Hello {name}!");
  }

  [Function(nameof(CronTest))]
  public async Task CronTest(
    [TimerTrigger("* * * * * *")] TimerInfo timerInfo,
    [DurableClient] DurableClientContext durableContext,
    FunctionContext context
  )
  {
    this.logger.Info($"Start: {context.FunctionId} {timerInfo}");
    var instanceId = await durableContext.Client.ScheduleNewOrchestrationInstanceAsync(nameof(HelloExample), "Justin");
    this.logger.LogInformation("Started: {instanceId}...", instanceId);

    var result = await durableContext.Client.WaitForInstanceCompletionAsync(instanceId, CancellationToken.None, true);
    this.logger.LogInformation("Result: {SerializedOutput}", result.SerializedOutput);
    await Task.CompletedTask;
  }
}

i have resolved the issue need register on program.cs

  services.AddDurableTaskClient(builder =>
        {
            // Configure options for this builder. Can be omitted if no options customization is needed.
            builder.Configure(opt => { });
            builder.UseGrpc(); // multiple overloads available for providing gRPC information

            // AddDurableTaskClient allows for multiple named clients by passing in a name as the first argument.
            // When using a non-default named client, you will need to make this call below to have the
            // DurableTaskClient added directly to the DI container. Otherwise IDurableTaskClientProvider must be used
            // to retrieve DurableTaskClients by name from the DI container. In this case, we are using the default
            // name, so the line below is NOT required as it was already called for us.
            builder.RegisterDirectly();
        });
