Detect intent not response fulfillment text

[Thắng Nguyễn]

Hello,

I am currently working with DialogFlow in Unity. I use UnityWebRequest to interact with the API. I don't get a text response even though intentDetectionConfidence = 1 was received. When I try with another agent my code is working fine, but it can't detect all my intent. This is the response I got

{

  "responseId": "731f02f2-5341-4ee7-ae13-7ecdf11ba699-9779ea79",

  "queryResult": {

    "queryText": "Chào",

    "action": "input.welcome",

    "parameters": {},

    "allRequiredParamsPresent": true,

    "intent": {

      "name": "projects/newagent-vvcn/agent/intents/c4bb07f9-5704-49cd-9806-7175b77e41a0",

      "displayName": "Default Welcome Intent"

    },

    "intentDetectionConfidence": 1,

    "languageCode": "vi-vn"

  },

  "outputAudioConfig": {

    "audioEncoding": "OUTPUT_AUDIO_ENCODING_LINEAR_16"

  }

}

Can someone help me?

Hello,
Addressing technical issues is more appropriate for the StackOverflow community, like this example. 

Please open a Private issue with the Dialogflow team or open a case with support. The Google Groups are reserved for general questions on Google Cloud Platform-end products. 

You should provide the agent zip and the reproduction steps. 

Also, please run the Agent Validation if you haven't done it already, to get suggestions on improving the quality and performance of your agent.
Thank you!
