Error Handling (VSK MM)

In the event of an error, you should return an error code in the response so that Alexa can take a specific action.

Structure of Error Messages

The payload of an ErrorResponse event must specify a type and a message.

  • type: One of the accepted type values that indicates the kind of error that has occurred. Alexa uses this attribute to respond to the customer appropriately.
  • message: String that provides more information about the error. This information is not shared with the customer.
