> Key: BEAM-7851
> URL: https://issues.apache.org/jira/browse/BEAM-7851
> Project: Beam
> Issue Type: Bug
> Components: io-java-gcp, runner-dataflow, runner-direct
> Reporter: Gregory Parsons
> Priority: P3

> Hi all,
> I have a potential issue I am debugging with
> `org.apache.beam.sdk.io.gcp.pubsub`. When using the GCP PubSub service no
> messages are received on the DirectRunner or the DataflowRunner when using
> PubsubIO.readStrings(). When using the DirectRunner and the Pubsub Emulator
> it works correctly locally.
> I have been working with this issue for the past few days and believe it may
> be related to the PubsubIO library.
>
> I am listening to a topic (also tried a subscription) using:
> {code:java}
> PubsubIO.Read<String> read = PubsubIO
> .readStrings()
> .withTimestampAttribute("timestamp")
> .fromTopic(options.getTopic());{code}
>
> Alternatively this method works:
> {code:java}
> PubsubIO.Read<PubsubMessage> read = PubsubIO
> .readMessagesWithAttributes()
> .withTimestampAttribute("timestamp")
> .fromTopic(options.getTopic()); {code}
> The code works perfectly with the Pubsub Emulator using readStrings() and
> after switching to readMessagesWithAttributes() everything works correctly on
> both the emulator as well as GCP.
>
> I am using Beam "2.13.0" with "beam-runners-google-cloud-dataflow-java" with
> Java 8.
> My "gcloud" versions:
> Google Cloud SDK 256.0.0
