   It is indeed an issue that need to be fixed
   
   ```java
       public void writeAttachments(Map<String, Object> attachments) throws IOException {
           if (attachments == null) {
               return;
           }
   
           Map<String, String> stringAttachments = new HashMap<>();
           attachments.forEach((k, v) -> stringAttachments.put(k, (String) v));
   
           ProtobufUtils.serialize(MapValue.Map.newBuilder().putAllAttachments(stringAttachments).build(), os);
           os.flush();
       }
   ```
