      Description

      With the following Single Message Transform: 

      "transforms.ExtractId.type":"org.apache.kafka.connect.transforms.ExtractField$Key",
      "transforms.ExtractId.field":"id"

      Kafka Connect errors with : 

      java.lang.NullPointerException
      at org.apache.kafka.connect.transforms.ExtractField.apply(ExtractField.java:61)
      at org.apache.kafka.connect.runtime.TransformationChain.apply(TransformationChain.java:38)

      There should be a better error message here, identifying the reason for the NPE.
