### What happened?
I'm creating some base classes to dynamically execute a workflow for some
tests. I create a workflow engine and then try to execute the wokrflow with the
following code:
```
IVariables variables = Variables.getADefaultVariableSpace();
ITwoWayPasswordEncoder passwordEncoder = Encr.getEncoder();
if(passwordEncoder == null) {
passwordEncoder = new HopTwoWayPasswordEncoder();
}
String metadataDirectory =
"C:\\hop\\config\\projects\\default\\metadata";
ILoggingObject log = new SimpleLoggingObject("WorkflowLog",
LoggingObjectType.WORKFLOW, null);
IHopMetadataProvider metadataProvider = new
JsonMetadataProvider(passwordEncoder, metadataDirectory, variables);
WorkflowMeta workflowMeta =
new WorkflowMeta(variables, directory+workflowName+".hwf",
metadataProvider);
IWorkflowEngine workflowEngine =
WorkflowEngineFactory.createWorkflowEngine(
variables, // see above
"local-config", // The name of the
run configuration defined in the metadata
metadataProvider, // The metadata provider
to resolve the run configuration details
workflowMeta, // The workflow metadata
log // The parent logging object
);
workflowEngine.setLogLevel(LogLevel.ERROR);
System.out.println("\nStarting workflow");
Result result = workflowEngine.startExecution();
```
Upon starting execution, I get the following error, from ExecutionBuilder:
2025/03/10 18:27:24 - Workflow Inbound - ERROR: **A serious error occurred
during workflow execution: Please specify execution type Pipeline or Workflow**
2025/03/10 18:27:24 - Workflow Inbound - ERROR: java.lang.AssertionError:

I'm not really familiar with the inner-workings of Hop but I looked at the
ExecutionBuilder class and see that the withExecutorType does the following:
```
public ExecutionBuilder withExecutorType(ExecutionType executionType) {
assert executionType != null : "Please specify execution type Pipeline
or Workflow, not null";
assert executionType == ExecutionType.Pipeline || executionType ==
ExecutionType.Workflow
: "Please specify execution type Pipeline or Workflow";
this.executionType = executionType;
return this;
}
```
Based on this, it doesn't seem possible for the LocalWorkflowEngine to ever
successfully call startExecution because in its beforeExecution() method, it
registers its execution with an ExecutorType of Action. Am I missing something
here?
