Troubleshoot UnknownResourceException when following AWS tutorial

I'm attempting to follow this AWS tutorial. But I'm having trouble at "You can run GreeterWorker successfully at this point." as I'm getting an UnknownResourceException.

Exception in thread "main" com.amazonaws.services.simpleworkflow.model.UnknownResourceException: Unknown domain: helloWorldWalkthrough (Service: AmazonSimpleWorkflow; Status Code: 400; Error Code: UnknownResourceFault; Request ID: xxxxx)

Steps taken

The tutorial didn't cover the step about attaching the SimpleWorkflowFullAccess policy to the AWS user, so I'm wondering if there is a similar undocumented step to allow my user to find this domain.

My code is copy/pasted from the GreeterWorker class in the tutorial.

import com.amazonaws.ClientConfiguration;
import com.amazonaws.auth.AWSCredentials;
import com.amazonaws.auth.BasicAWSCredentials;
import com.amazonaws.services.simpleworkflow.AmazonSimpleWorkflow;
import com.amazonaws.services.simpleworkflow.AmazonSimpleWorkflowClient;
import com.amazonaws.services.simpleworkflow.flow.ActivityWorker;
import com.amazonaws.services.simpleworkflow.flow.WorkflowWorker;

public class GreeterWorker  {
   public static void main(String[] args) throws Exception {
     ClientConfiguration config = new ClientConfiguration().withSocketTimeout(70*1000);

     String swfAccessId = System.getenv("AWS_ACCESS_KEY_ID");
     String swfSecretKey = System.getenv("AWS_SECRET_KEY");
     AWSCredentials awsCredentials = new BasicAWSCredentials(swfAccessId, swfSecretKey);

     AmazonSimpleWorkflow service = new AmazonSimpleWorkflowClient(awsCredentials, config);
     service.setEndpoint("https://swf.us-east-1.amazonaws.com");

     String domain = "helloWorldWalkthrough";
     String taskListToPoll = "HelloWorldList";

     ActivityWorker aw = new ActivityWorker(service, domain, taskListToPoll);
     aw.addActivitiesImplementation(new GreeterActivitiesImpl());
     aw.start();

     WorkflowWorker wfw = new WorkflowWorker(service, domain, taskListToPoll);
     wfw.addWorkflowImplementationType(GreeterWorkflowImpl.class);
     wfw.start();
   }
}

I was also facing the same issue and then I found that the region is hard coded in the main method inside GreeterWorker class as shown below:

service.setEndpoint("https://swf.us-east-1.amazonaws.com");

However my SWF account was in west-2 region.

You need to create the domain using the console or through an api call. Domain is not created automatically.
