Subsequent invocations will only occur if a call to ServletOutputStream.isReady() has returned false and it has since become possible to write data.
    
    Throws:
    
    IOException - if an I/O error occurs while processing this event
  - onError
```
void onError(Throwable throwable)
```
    Invoked if an error occurs while writing the response.
