Hello, I am new to Grpc and so far like it very much. I am using a bidirectional stream and from time to time I get an exception like this one:
io.grpc.StatusRuntimeException: CANCELLED: Failed to read message. at io.grpc.Status.asRuntimeException(Status.java:526) at io.grpc.stub.ClientCalls$StreamObserverToCallListenerAdapter.onClose(ClientCalls.java:418) at io.grpc.ForwardingClientCallListener.onClose(ForwardingClientCallListener.java:41) at io.grpc.internal.CensusStatsModule$StatsClientInterceptor$1$1.onClose(CensusStatsModule.java:663) at io.grpc.ForwardingClientCallListener.onClose(ForwardingClientCallListener.java:41) at io.grpc.internal.CensusTracingModule$TracingClientInterceptor$1$1.onClose(CensusTracingModule.java:392) at io.grpc.internal.ClientCallImpl.closeObserver(ClientCallImpl.java:443) at io.grpc.internal.ClientCallImpl.access$300(ClientCallImpl.java:63) at io.grpc.internal.ClientCallImpl$ClientStreamListenerImpl.close(ClientCallImpl.java:525) at io.grpc.internal.ClientCallImpl$ClientStreamListenerImpl.access$600(ClientCallImpl.java:446) at io.grpc.internal.ClientCallImpl$ClientStreamListenerImpl$1MessagesAvailable.runInContext(ClientCallImpl.java:510) at io.grpc.internal.ContextRunnable.run(ContextRunnable.java:37) at io.grpc.internal.SerializingExecutor.run(SerializingExecutor.java:123) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) at java.lang.Thread.run(Thread.java:748) Caused by: io.grpc.StatusRuntimeException: INTERNAL: Invalid protobuf byte sequence at io.grpc.Status.asRuntimeException(Status.java:517) at io.grpc.protobuf.lite.ProtoLiteUtils$2.parse(ProtoLiteUtils.java:168) at io.grpc.protobuf.lite.ProtoLiteUtils$2.parse(ProtoLiteUtils.java:82) at io.grpc.MethodDescriptor.parseResponse(MethodDescriptor.java:265) at io.grpc.internal.ClientCallImpl$ClientStreamListenerImpl$1MessagesAvailable.runInContext(ClientCallImpl.java:498) ... 5 more Caused by: com.google.protobuf.InvalidProtocolBufferException: Protocol message contained an invalid tag (zero). at com.google.protobuf.InvalidProtocolBufferException.invalidTag(InvalidProtocolBufferException.java:105) at com.google.protobuf.CodedInputStream$ArrayDecoder.readTag(CodedInputStream.java:646) at com.zepl.notebook.service.grpc.NotebookResponse.<init>(NotebookResponse.java:46) at com.zepl.notebook.service.grpc.NotebookResponse.<init>(NotebookResponse.java:13) at com.zepl.notebook.service.grpc.NotebookResponse$1.parsePartialFrom(NotebookResponse.java:2851) at com.zepl.notebook.service.grpc.NotebookResponse$1.parsePartialFrom(NotebookResponse.java:2846) at com.google.protobuf.AbstractParser.parseFrom(AbstractParser.java:91) at com.google.protobuf.AbstractParser.parseFrom(AbstractParser.java:49) at io.grpc.protobuf.lite.ProtoLiteUtils$2.parseFrom(ProtoLiteUtils.java:173) at io.grpc.protobuf.lite.ProtoLiteUtils$2.parse(ProtoLiteUtils.java:165) ... 8 more I enabled netty debug logs, and I have this line: [id: 0xfc5978c0, L:/100.119.42.167:39090 - R:--/--] OUTBOUND RST_STREAM: streamId=1539 errorCode=8. I dont really get what is wrong, I get this error once in a while and I am stuck. I am calling the observers from different threads in the server side, do I need to synchronize the method that calls the observers?
