KB226862: Trying to add new Contact Group member shows “ImageCombo1” and editing existing contacts fails with error “Object with ID XXX and type 34 (user) is not found in the metadata” in MicroStrategy Developer 9.4.x

Object with ID XXX and type 34 (user) is not found in the metadata

 
STEPS TO REPRODUCE
1) Create a contact and user, and link the contact to the user.
2) Create a history list subscription for this user.
3) Delete this user (from search result window), then the issue is reproduced.
4) The contact is still there, but when editing it, the error appears regarding “Object with ID XXX and type 34 (User) is not found in metadata.”
5)  When trying to add new members to a contact group, “Imagecombo1” displays.
 
CAUSE
This is a known issue in Strategy Developer 9.4.x.  The issue occurs when a user/contact has been added to a subscription and then the user object is deleted but the contact object is not.  It leads to this issue because contact objects cannot be associated with a subscription unless they are linked to a user object, which is no longer the case after the user has been deleted.
 
ACTION
Currently this issue is still being reviewed for feasibility by our Technology team and it is not scoped for any upcoming scheduled Strategy release. 
 
WORKAROUND
Deleting the now invalid Contact object will resolve the issue.  If assistance is needed in identifying the invalid Contact Objects, please contact Strategy Technical Support for further instructions.
