CM4SF_CUSTOM_MAPPINGS_INVALID_FIELD

A field mapped from Campaign Monitor to Salesforce is invalid. It's possible the field has been mapped to the wrong data type. i.e. you can't map a text field to a number field. This exception can occur when syncing from Campaign Monitor back into Salesforce. The incorrectly mapped field will be displayed alongside the maintenance log.
