URL: https://github.com/apache/pulsar/issues/24121

   ### Search before asking
   
   - [x] I searched in the [issues](https://github.com/apache/pulsar/issues) and found nothing similar.
   
   
   ### Motivation
   
   When an error occurs during the sending of a message using `NewOutputMessage`, the go function exits with a panic. This behavior prevents the application from handling the error gracefully, as it bypasses any error-handling logic.
   
   Errors should be returned by `NewOutputMessage `so they can be handled by the calling code, rather than causing a panic.
   
   ### Solution
   
   Adapt the outputMessage in the context as following
   
   ```go
   	goInstance.context.outputMessage = func(topic string) (pulsar.Producer, error) {
   		producer, err := goInstance.getProducer(topic)
   		if err != nil {
   			log.Errorf("getting producer failed, error is:%v", err)
   			return nil, err
   		}
   		return producer, nil
   	}
   ```
