Receivables Aging by General Ledger Account Report - seeded Datamodel not working

Summary:

I have been able to customize the Receivables Aging by General Ledger Account Report to be more usefull, by using the seeded datamodel and creating a new report instead of the scheduled, to get a report that is excel-friendly…

But all of a sudden it has startet giving me this error message:

To be totally clear, I am not customizing the datamodel, only creating my own report from the seeded datamodel.

The scheduled report is still working perfectly fine, but is still just as useless as it has always been 😆

Does anyone know what the problem is? Or has any idea on what to do to overcome it?
