oci streaming java sdk error-handling Java

I'm attempting to set up I'm currently working on a project that uses Oracle Cloud Infrastructure (OCI) Streaming to handle event processing. I've set up a stream and I'm able to push messages to it without any issues. However, when I try to consume messages using the OCI Java SDK (version 2.8.0), I encounter an `Invalid Message Format` behavior. My consumer code looks like this: ```java import com.oracle.bmc.streaming.StreamClient; import com.oracle.bmc.streaming.model.Message; import com.oracle.bmc.streaming.requests.GetMessagesRequest; import com.oracle.bmc.streaming.responses.GetMessagesResponse; StreamClient streamClient = new StreamClient(client); GetMessagesRequest request = GetMessagesRequest.builder() .streamId(streamId) .build(); GetMessagesResponse response = streamClient.getMessages(request); List<Message> messages = response.getMessages(); for (Message message : messages) { System.out.println(new String(message.getValue())); } ``` I verified that the messages I am sending are in the correct JSON format and are encoded properly. Here’s a sample payload I’m sending: ```json {"event":"user_signup", "user_id":"12345"} ``` I've also checked the message schema and am fairly certain that it matches what is expected by the consumer. To troubleshoot, I tried using a simple string message instead of JSON: ```java String messagePayload = "Hello World"; streamClient.putMessage(PutMessageRequest.builder() .streamId(streamId) .putMessageDetails(PutMessageDetails.builder() .value(messagePayload.getBytes()) .build()) .build()); ``` However, I still receive the same `Invalid Message Format` behavior. I’ve tried adjusting the message size and encoding settings without success. Any insights into common pitfalls that could be causing this would be appreciated, particularly if there are any specific configurations or best practices when using the OCI Streaming SDK in a Java application. Thanks for your help! How would you solve this? I'm working with Java in a Docker container on Linux. I'd really appreciate any guidance on this. For reference, this is a production service. Any ideas how to fix this?
