   at least in node, and i'd imagine you can do something similar in Java, if you wrap the `send` method you'll have the `msg` in scope for your catch method to do whatever you want with on error.
   
   ```
   exports.publish = async function(message, timestamp) {
     const producer = await client.createProducer(producerConfig);
     const msg = {
       data: Buffer.from(message),
       eventTimestamp: timestamp
     };
   
     producer.send(msg).catch(function(err) {
       log.error({ message: `Error publishing: ${err}; dropping message`,  msg: msg });
     });
   }; 
   ```
