             Summary: Improve Beam Fn API Artifact Staging Service Error Handling
                 Key: BEAM-5454
                 URL: https://issues.apache.org/jira/browse/BEAM-5454
             Project: Beam
          Issue Type: Improvement
          Components: java-fn-execution
            Reporter: Axel Magnuson
            Assignee: Axel Magnuson


I noticed that the onComplete logic is not wrapped in a try/catch block.  This led to an
uncaught NPE in a problem I was debugging.  It also does not log errors, preferring to just
use the observer's callback to pass these errors to the SDK.  However some SDKs such as golang's
do not surface these errors, and they get lost.
