pub a message with ordering key error, keep getting : "Execution cancelled because executing previous runnable failed"

[wsyzwddsg111]

we are keep getting this error: "Execution cancelled because executing previous runnable failed" , when pub a ordered msg

BUT I don't know what the error is, I cant find the root cause like IO/network issue/500 or any other useful info.

I could only see the "Execution cancelled because executing previous runnable failed"

why dont pubsub print the first error detail?

code is like :

try {
      Publisher publisher = Publisher.newBuilder(TopicName.of(projectId, topicId)).setEnableMessageOrdering(true).build();

  PubsubMessage message = PubsubMessage.newBuilder().setOrderingKey("test-key").setData(data).build();
  System.out.println("Publishing message: " + message);

  ApiFuture<String> future = publisher.publish(message);
  System.out.println("Published message ID: " + future.get());

} catch(Exception e){
 log.error("error ->",e);
}
