   The problem is in the call to `PartitionKey.partition`, where this assumes that the data value from the Generic object model can be used for a partition key. It can't because the two use different representations. Generics use Java 8 date/time classes and internals (manifest writers in this case) expect the long micros representation.
   
   You just need to wrap the record in `InternalRecordWrapper` when passing it to the `partition` method, which will convert between the different representations. You can reuse the wrapper.
