I want to read a ecore.model.

My mwe-File ist

module org.demo02.GenWorkflow
	import org.eclipse.emf.mwe.utils.*
	var  workspacePath = "/Users/alle/eclipse/ws/redVoodo/demo/"
	var  runtimeProject = "org.demo02"
	var targetDir = "src-gen"
	var  modelFolder = "model"
	var  modelPath = "${workspacePath}/${runtimeProject}/${modelFolder}"

Workflow {
	component = DirectoryCleaner {
        directory = targetDir
    }

	component = org.eclipse.xtext.ecore.EcoreSupport {}
  	component = org.eclipse.xtext.mwe.Reader {
  		//  path to scan for models
  		path = modelPath
  		// by default necessary
		register = org.demo02.GenSetup {}
		loadResource = {
			slot = "model"
		}
  	}
  
 	component = org.eclipse.xtext.generator.GeneratorComponent {
		register = org.demo02.GenSetup {}
		slot = 'model'
		outlet = {
			outletName = "jpa"
			path = "${workspacePath}/${runtimeProject}/${targetDir}"
		}
	}
}

I get the following error:
ERROR mf.mwe2.launch.runtime.Mwe2Launcher - Problems running workflow org.demo02.GenWorkflow: A slot with name 'DEFAULT_OUTPUT' has not been configured.

Hi, you have to additionally add a outlet without a name. Regards

I have done it:

module org.demo02.GenWorkflow
	import org.eclipse.emf.mwe.utils.*
	var  workspacePath = "/Users/alle/eclipse/ws/redVoodo/demo/"
	var  runtimeProject = "org.demo02"
	var targetDir = "src-gen"
	var  modelFolder = "model"
	var  modelPath = "${workspacePath}/${runtimeProject}/${modelFolder}"

Workflow {
	component = DirectoryCleaner {
        directory = targetDir
    }

	component = org.eclipse.xtext.ecore.EcoreSupport {}
  	component = org.eclipse.xtext.mwe.Reader {
  		//  path to scan for models
  		path = modelPath
  		// by default necessary
		register = org.demo02.GenSetup {}
		loadResource = {
			slot = "model"
		}
  	}
  
 	component = org.eclipse.xtext.generator.GeneratorComponent {
		register = org.demo02.GenSetup {}
		slot = 'model'
		outlet = {
			outletName = "jpa"
			path = "${workspacePath}/${runtimeProject}/${targetDir}"
		}
		outlet = {
			
		}
	}
}

But now I get the following error:
ERROR mf.mwe2.launch.runtime.Mwe2Launcher - Problems running workflow org.demo02.GenWorkflow: The path of outle 'DEFAULT_OUTPUT' was null
