I have the following error, and cant figure out how to solve it. I cant find the item in the error anywhere in my datamodell. I have tried duplicating the app an systematically gone through every datasource, and deleted them, to no avail. Now the app is completely stripped and I’m still getting the error.

What triggers this error?  
How did this happen?  
How can I locate the duplicates?  
How do I fix it and prevent it from happening again?

I have found the object class “Krpo4e”, but if I include it in the app, the app fails to load initial data so I cannot manipulate the data inn the app
