.NET DevUI Is it possible to run workflow without AI Agent ?

[VladyslavLishchyna]

Hi, I build test workflow that don`t use any AI agents its just 3 simple executor, when I try run it in Dev UI I have exception that I need register AI agent for it, but I just want to trigger my workflow

public static class InTestFeaturesRegistrations
{
  public static WebApplicationBuilder AddInTestFeatures(this WebApplicationBuilder builder)
  { 
    builder
      .AddWorkflow("Test", TestWorkflowFactory.Create);

    builder
      .Services
      .AddSingleton(new StartReleaseExecutor())
      .AddSingleton(new ExecutorB())
      .AddSingleton(new ExecutorC());

    return builder;
  }

  public static class TestWorkflowFactory
  {
    public static Workflow Create(IServiceProvider sp, string name)
    {       
      var executorA = sp.GetRequiredService<StartReleaseExecutor>();
      var executorB = sp.GetRequiredService<ExecutorB>();
      var executorC = sp.GetRequiredService<ExecutorC>();

      var builder = new WorkflowBuilder(executorA);

      builder
        .WithName(name)
        .AddEdge(executorA, executorB)
        .AddEdge(executorB, executorC)
        .WithOutputFrom(executorC);

      return builder.Build();
    }
  }

  public class StartReleaseExecutor() : Executor<string, string>("StartReleaseExecutor")
  {
    public override async ValueTask<string> HandleAsync(string message, IWorkflowContext context, CancellationToken ct = default)
    {
      await Task.Delay(5000);
      return "";
    }
  }

  public class ExecutorB() : Executor<string, string>("ExecutorB")
  {
    public override async ValueTask<string> HandleAsync(string message, IWorkflowContext context, CancellationToken ct = default)
    {
      await Task.Delay(5000);
      return "";
    }
  }

  public class ExecutorC() : Executor<string, string>("ExecutorC")
  {
    public override async ValueTask<string> HandleAsync(string message, IWorkflowContext context, CancellationToken ct = default)
    {
      await Task.Delay(5000);
      return "";
    }
  }
}
