This is the human-readable description accompanying the remote invocation error code above, for this same endpoint's sync attempt. An admin reads this text directly rather than looking up the numeric code, since it typically spells out in plain language what the peer fabric interconnect objected to when this endpoint's VLAN or VSAN binding tried to sync across. A value like 'Remote invocation failed: object not found' tells the admin the peer side doesn't yet have a matching object to sync this endpoint's state against.
