"Attempting to retrieve the CollectionKeyId for caption <x> failed" after adding a new field when Locker objects already exist

On a system with existing Locker records I added a new field to an Adapter, Locker and Link mapping, and then ran Changes Synchronization, which logged an error.  I then ran a Clear Sync Changes, followed by a Baseline Synchronization, but the same error still occurred.

I managed to get rid of the error by running Clear Entities on the Locker, which isn't ideal since I lost all my joins and had to careful resync my Links in the right order to avoid any undesirable provisioning attempts :-(

Synchronization job started syncing 42941 changes on the 'Chris21 DET' link from the adapter to locker. Job ID: b7478421-d9c7-405d-a286-290d823cd3eb",Normal
