I was able to reproduce this in a test project and I’ve filed a ticket with Mendix.
Ticket Number: 80544
The way I was able to reproduce this was deleting an object that was displayed in a dataview over an association to another dataview that was listening to a grid.
Edit: Support just got back to me and they said a fix for this will be in 7.23.2. A release date has not been made yet.
I have the same in 7.23. What is the status of the ticket?
We are also experiencing this in 7.22 and 7.23 when opening pages via microflows. We do not get this message again after adding a Close Page in the microflow, before opening the new page.
Status of the bug would be great - as i have the same in 7.23 ...
Same problem here. Every single time… what can I do?
Any update would be much appreciated!
Have same issue in 7.22.2. Is there an ETA on delivering a fix?
Facing the same issue in 7.23.1
When I select one row, and delete it. It’s getting deleted.
But, it’s always throwing pop up error as: An error has occurred, please contact your system administrator.

Anyone know what causes this error?
Thanks

In my case it happened when I had the following object model:
In my page I had conditional visiblity on all three entities. When switching of the deletion of Content when deleting TableofContent the error happened. I have added the deletion of the content when deleting the tableof content and than the error doesn't popup.
I hope this will help in solving your problems...
