If there is an invalid attribute in the filter (for example, one for which Schema Mapping is not defined), the following happens:
- At each polling loop, the Publisher fails to synchronize the class that contains the invalid attribute, and gives an error indicating an unsupported attribute.
- The driver is still able to start.
- The Subscriber channel still functions correctly unless the invalid attribute is referenced. A task that references an invalid attribute gives an error and is not successful.
The sample driver configuration supports the standard attributes in Exchange, so this issue could occur only for custom attributes you have added in Exchange.
