GCP Dataflow Job scenarios with 'InvalidArgument' scenarios When Reading from Pub/Sub Subscription
I'm working with a frustrating scenario with my Google Cloud Dataflow job when trying to read messages from a Pub/Sub subscription. The job starts processing but fails after a few minutes with the following behavior message: ``` InvalidArgument: Request contains an invalid argument. ``` I'm using the Apache Beam SDK version 2.35.0 with Java 11, and my Dataflow pipeline is supposed to read messages from a Pub/Sub subscription and then write them to BigQuery. Here's a snippet of the code I'm using to create the Pub/Sub source: ```java PipelineOptions options = PipelineOptionsFactory.create(); Pipeline p = Pipeline.create(options); p.apply("ReadFromPubSub", PubsubIO.readStrings().fromSubscription("projects/my-project/subscriptions/my-subscription")) .apply("TransformData", ParDo.of(new MyTransformationFunction())) .apply("WriteToBigQuery", BigQueryIO.writeTableRows() .to("my-project:my_dataset.my_table") .withSchema(myTableSchema) .withCreateDisposition(CreateDisposition.CREATE_IF_NEEDED) .withWriteDisposition(WriteDisposition.WRITE_APPEND)); ``` I’ve double-checked that the subscription exists and that my Dataflow service account has the necessary permissions to access both Pub/Sub and BigQuery. In Pub/Sub, I verified that the messages are available for consumption, but I need to seem to understand why this behavior is occurring after some time. I also noticed that the behavior logs show "No matching subscriptions found" at times, which seems odd since I can confirm that the subscription is active and has messages. I've tried rerunning the job multiple times with no changes in the underlying configuration but still face the same scenario. Does anyone have insights into why this might be happening or any suggestions on debugging steps? Any help would be greatly appreciated! Am I approaching this the right way?
