Any suggestions why I get this error and ways to fix/troubleshoot it?  
A different app in the same solution loads fine.

I made a copy of the app and started deleting datasources until I found the one that was causing the error. Now that I’ve found the object-class how do i fix it??

Hi!

This is a new type of error I have never seen before. So both the reason and the solution is currently unknown. Can you provide info about which solution this is in a DM, and we’ll take a look!

Error found. Seems like duplicating the same object class twice has generated non-unique collection names (table names). Solved.
