> When running a PubsubIO-fed pipeline on a local machine, the pipeline runs for 10sec
and then fails with a NPE (I'd guess when trying to ACK messages?). 
> Logs confirm I am successfully reading messages and writing them out to pubsubIO, at
least for a while.
> Stack trace: 
> Exception in thread "main" java.lang.NullPointerException
