Hi Eva,

I am not able to reproduce the error at all while logged in as a Project or a Folder Admin user.

I was able to test this on LabKey 18.3.2 successfully.

Looking at the stack error, it appears to be tied to the pipeline module.

What exactly is inside of these folders that the user is attempting to delete exactly? Are they studies? Assays? What happens if you try to have them delete the objects inside of the folder before trying to delete the folder itself? If the user creates a new folder, can they immediately delete it soon after?

Regards,

Jon
