Issue/Introduction

WSS administrator fails to push updated policy out via UPE

Updated WSS policies not available on WSS after push from UPE

WSS policy fails to install with "Could not install field 'summary' in exception exception.coach" error reported in UPE logs

Above error field 'summary' may also be something else, like 'contact', 'details', 'format' or 'help'

Problem only appears when WSS Policy includes exception pages

Environment

WSS Administration performed via Management Center integration

WSS Policies using available built in (not custom) exceptions e.g. exception.coach

Cause

The above policy load error is due to the customer SG having some of the builtin exception fields changed in their exception configuration, while the classifier/pod SG not allowing changes to fields of builtin exceptions.

The 'coach' exception in the above case is an example of such an exception, which results in migrated policy not loading in the WSS proxy.

Resolution

Reset those offending exception fields to default (empty) as reported in the errors within UPE, and redo the policy migration through MC classifier interface again.
