Hi [~rhauch],

I would like to pick this Jira up. Wanted some advice on the error message .I 
am thinking , if the exception occurred during:
 a) keyAndSchema conversion,  then error msg logged as :  Failed to convert 
Record Key to Kafka Connect format.

b) valueAndSchema conversion, then error msg logged as : Failed to convert 
Record Value to Kafka Connect format.

And Main ConnectException thrown as :  Exiting WorkerSinkTask due to 
unconvertedmessage exception.

Any help on the hint message to fix the issue would be great?

> Connect was configured for Avro key and value but data had String key and 
> Avro value. The resulting error message was misleading because it didn't 
> distinguish key from value, and so I was chasing problems with the value 
> instead of the key.
> tl;dr Connect should at least tell you whether the problem is with 
> deserializing the key or value of a record
