NewCreateProcessInstanceCommand with result not works ?

[ArgoTown]

@Zelldon any suggestion how to solve this ?

In docker i pulled latest of zeebe (camunda/zeebe:latest - v8.5.6) image and I used simple code, to start the proccess and get the result of a task

Worker

public static class JobWorker

    public static async Task Test(IJobClient client, IJob activatedJob)
    {
        await client
            .NewCompleteJobCommand(activatedJob)

But instead i'm getting

Registered as singleton:

builder.Services.AddSingleton(
ZeebeClient
.Builder()
.UseGatewayAddress("http://localhost:26500")
.UsePlainText()
.UseKeepAlive(TimeSpan.FromSeconds(15))
.Build());

Expected result a success with variables provided in the response, any idea why ?

Hey @ArgoTown,

• Was it running before? Did you try it with a earlier version?
• Could you please try without the protocol http://
• Can you try 0.0.0.0

[ArgoTown]

Yes version 8.5.6 and currently tried example, when i put .WithResult() your example ends up to the same error.

[ArgoTown]

Ok weird thing i played around and seems it works if worker defined like in your example and .WithResult() passed.

zeebeClient
.NewWorker()
.JobType("test")
.Handler(JobWorker.Test)
.MaxJobsActive(5)
.Name(nameof(JobWorker))
.AutoCompletion()
.PollInterval(TimeSpan.FromSeconds(1))
.Timeout(TimeSpan.FromSeconds(10))
.Open();

[Zelldon]

Maybe try to remove the lines now one by one to see which was it, maybe we have to open a bug.

But i think it is the max Active

[ArgoTown]

As i mentioned previously MaxJobsActive not a game changer, i tested removing these methods and just .AutoCompletion() have no impact, but if i remove any of these .MaxJobsActive(5), .PollInterval(TimeSpan.FromSeconds(1)), .Timeout(TimeSpan.FromSeconds(10)), then it not works, result the same in error.

[Zelldon]

Thanks 👍 i will take a look
