Don't know how to send values to azure function via cloudscript with Unity

Hello!! I create azure function in portal named <HttpTrigger1>, a basic Trigger

#r "Newtonsoft.Json"

using System.Net;
using Microsoft.AspNetCore.Mvc;
using Microsoft.Extensions.Primitives;
using Newtonsoft.Json;

public static async Task<IActionResult> Run(HttpRequest req,  ILogger log)
{
    log.LogInformation("C# HTTP trigger function processed a request.");

    string name = req.Query["name"];
    //string name = customerName;

    string my = "aaa";

    string requestBody = await new StreamReader(req.Body).ReadToEndAsync();
    dynamic data = JsonConvert.DeserializeObject(requestBody);
    name = name ?? data?.name;

    string responseMessage = string.IsNullOrEmpty(name)
        ? "This HTTP triggered function executed successfully. Pass a name in the query string or in the request body for a personalized response."
                : $"Hello, {name}. This HTTP triggered function executed successfully.";

            return new OkObjectResult(responseMessage);
}

and follow

add to Unity. Using Cloudscript and want to send name = "Lisa"

using System.Collections.Generic;
using UnityEngine;
using PlayFab;
using PlayFab.CloudScriptModels;


public class PlayfabCloudFun : MonoBehaviour
{
    public string functionName = "HttpTrigger1";


    public void CallCSharpExecuteFunction()
    {
        PlayFabCloudScriptAPI.ExecuteFunction(new ExecuteFunctionRequest()
        {
            Entity = new PlayFab.CloudScriptModels.EntityKey()
            {
                Id = PlayFabSettings.staticPlayer.EntityId, //Get this from when you logged in,
                Type = PlayFabSettings.staticPlayer.EntityType, //Get this from when you logged in
            },
            FunctionName = functionName, //This should be the name of your Azure Function that you created.
            FunctionParameter = new Dictionary<string, object>() { { "name", "Lisa" } }, //This is the data that you would want to pass into your function.
            GeneratePlayStreamEvent = false //Set this to true if you would like this call to show up in PlayStream
        }, (ExecuteFunctionResult result) =>
        {
            if (result.FunctionResultTooLarge ?? false)
            {
                Debug.Log("This can happen if you exceed the limit that can be returned from an Azure Function, See PlayFab Limits Page for details.");
                return;
            }
            
            Debug.Log($"The {result.FunctionName} function took {result.ExecutionTimeMilliseconds} to complete");
            Debug.Log($"Result: {result.FunctionResult.ToString()}");
        }, (PlayFabError error) =>
        {
            Debug.Log($"Opps Something went wrong: {error.GenerateErrorReport()}");
        });
    }
}

But it always print

Result: This HTTP triggered function executed successfully. Pass a name in the query string or in the request body for a personalized response.

How can't I send data to HttpTrigger1?

thanks a lot^^
