 Review comment:
   It looks like Guavas 20 and Guava 26 Base64 didn't allow nulls so checking 
getData should be fine replacement for prior logic.
   
   It may also be that the test is wrong and should have really called 
encodeData with an empty byte array to get the no data case for testing but it 
is unclear from the pubsub documentation what the contents of the field maybe 
so this is the safer route.
