Hi, I am having IndexError in some of my folders when i tried to view the content of Zcatalog created in these folders, but to my surprise this is not happening in other folders with similar Zcatalog. I am also not experiencing the same problem with objects of the old Zcatalog that I have catalog before this error. In an attempt to correct this error, i had duplicated the old Zcatalog and renamed it. But once i catalog the objects and try to view it, it will show the IndexError again.
