HTTP/1.1 400 Bad Request Error when executing PostRequest()

[SurferLab]

Hello,

The error comes after the step 5 of the tutorial uniFlow: Dialogflow V2 Unity Plugin Prototype : https://itp-xstory.github.io/uniFlow/#step5

I changed the post request routine as following : PostRequest("https://dialogflow.googleapis.com/v2/projects/my_project_name/agent/sessions/34563:detectIntent", my_token_from_previous_steps)); and also in the bottom as described in the video. But, when running the example in unity i get the following 03 outputs :
################################################

"queryInput": {
"audioConfig": {
"audioEncoding": 0,
"sampleRateHertz": 0,
"languageCode": "",

}

The mentionned lines from the NewScript.cs script are :

51 : Debug.Log(postRequest.responseCode);
52 : Debug.Log(postRequest.error);

I'm using unity 2019.3.7f1 in Windows10-x64, and i followed the tutorial step by step, could you help please ?
