I am trying to trigger Alexa to begin a dialog so that she asks the user to give the required slots for a given intent. I have made a language model such that DiagnosisIntent has 2 required slots. And I have added a dialog with prompts for those slots.

    "languageModel": {
      "invocationName": "diagnose",

        {

            }
          ],

            "{age}",

            "I'm {age} years old",
            "I was born {age} years ago",
            "I am the old age of {age}",
            "I am the ripe old age of {age}"
          ]
        },

                "elicitation": "Elicit.Slot.1323207333291.563366041005"
              }
            }
          ]
        }
      ]
    },
    "prompts": [
      {
        "id": "Elicit.Slot.1323207333291.854898796228",
        "variations": [
          {
            "type": "PlainText",
            "value": "How old are you?"
          }
        ]
      },
      {
        "id": "Elicit.Slot.1323207333291.563366041005",
        "variations": [
          {
            "type": "PlainText",
            "value": "Are you male of female?"
          }
        ]
      }
    ]
  }
}

I want to trigger this dialog from the LaunchHandler.handle() method. From what I understand, I do this using the following code:

Intent chainedIntent = Intent.builder().withName("BeginDiagnosisIntent").build();

return handlerInput.getResponseBuilder()
    .addDelegateDirective(chainedIntent)
    .build();

I expect this to cause Alexa to use the prompt to ask me for one of the slots that has not been filled yet. But instead, this response is generated and Alexa says There was a problem with the requested skill's response.

{
    "body": {
        "version": "1.0",
        "response": {
            "directives": [
                {
                    "type": "Dialog.Delegate",
                    "updatedIntent": {
                        "name": "BeginDiagnosisIntent",
                        "slots": {}
                    }
                }
            ],
            "type": "_DEFAULT_RESPONSE"
        },
        "userAgent": "ask-java/2.16.0 Java/11.0.7"
    }
}
