[GitBox <gi...@apache.org>]

damccorm opened a new issue, #20905:
URL: https://github.com/apache/beam/issues/20905

   Reading from a Pub/Sub Lite subscription using PubsubLiteIO fails with DataflowRunner. It works in DirectRunner. 
   
   ```
   
   import org.apache.beam.sdk.io.gcp.pubsublite.PubsubLiteIO;
   //..
       pipeline
           .apply("Read
   From Lite", PubsubLiteIO.read(subscriberOpitons))
           .apply("Convert and print", MapElements.into(TypeDescriptors.strings()).via(
   
              (SequencedMessage sequencedMessage) -> {
                 String data = sequencedMessage.getMessage().getData().toStringUtf8();
   
                LOG.info("Received: " + data);
                 return data;
               }
           ));
   
   ```
   
   
   ```
   
   java.lang.UnsupportedOperationException: BundleFinalizer unsupported by non-portable Dataflow.
