Intent returning Null for Rasa nlu

I am currently running into an issue where if the user types a word that has not been trained in the nlu file, the nlu will return this:

"intent": {
   "name": null,
   "confidence": 0.0
}

With other scenarios, it works great! Is there a way to capture these errors and have rasa return the default error message? Please let me know. Thank you!

It is unclear how you are using this nlu response.

  1. If you are using it in rasa_core, you can capture & handle any such intent beforehand in your Custom Action Class. e.g. 
def run(self, dispatcher, tracker, domain):
        intent  = tracker.latest_message.intent["name"]
  1. If you want to do it at rasa_nlu level itself, go to rasa_nlu installation directory (usually it is in "Python install folder"\Lib\site-packages\rasa_nlu\ and make below changes in model.py
def default_output_attributes():
        return {"intent": {"name": None, "confidence": 0.0}, "entities": []}

to

 def default_output_attributes():
        return {"intent": {"name": "YOUR_CUSTOM_NAME", "confidence": 0.0}, "entities": []}

But please be cautioned in using second one. You may have to take care while upgrading rasa_nlu python package.
