Two new sync error types

Two new error types are returned during synchronisation: UnknownConnectorError and UnhandledConnectorError.

What they mean

• UnknownConnectorError — the connector is not recognised
• UnhandledConnectorError — the connector failed in a way it does not yet account for

Action required

None, but if you branch on error type, these are two new values to expect. A sync that previously surfaced as a generic failure may now name one of these.
