Excel export from microflow - inputparameter

Hi!   I am trying to export data to excel using the Excel Exporter module and follow the steps shown in the Mendix Academy 7.3 (Import/Export Data). Goal: Export a list of resources with attributes to an excel file.   The first microflow with a list of resources as input:   The sub-microflow called:   It fails at “GenerateExcelDoc”:   com.mendix.modules.microflowengine.MicroflowException: com.mendix.systemwideinterfaces.MendixRuntimeException: com.mendix.core.CoreException: Cannot create excel, because the inputobject isn't a subclass of configured. Expect: X.Resource Retrieved: X.ResourceExcelDocument at X.mf_export_to_excel (JavaAction : 'GenerateExcelDoc') at X.mf_getData (SubMicroflow : 'mf_export_to_excel')   As shown in the Academy example the output document and input object should be both “ResourceExcelDocument” (and there is no Resource object available to be selected as input).   What do I need to change to make that work?

Your Resource objects must be associated to an InputObject (a container if you will). This InputObject must be set as “InputObject” in the “GenerateExcelDoc” Java action. I suppose that you did set your “ExcelResourceDocument” as input instead.

Edit: adding screenshots:

Domain model should look something like this:

Java Action should be configured like this:
