[Zope] Access error with "manage_copyObjects / manage_pasteObjects" with proxy roles

Hi, I'm getting the following error when I try to run a script via a non-manager proxy role (running the script as a manager works fine): *Error Type: Unauthorized* *Error Value: You are not allowed to access 'manage_copyObjects' in this context* *I'm using v2.8.1*, and there is no traceback about this error in the event log. Any help would be appreciated. TIA, AnThu
