Hi,

I've managed to get a HttpPost call working from a javascript application, however the moment I add pararmeters to the method and fetch request it always returns a failed response.

using System;
using System.Collections.Generic;
using System.Web.Mvc;
using System.Web.Script.Serialization;
using Umbraco.Core;
using Umbraco.Core.Composing;
using Umbraco.Core.Models;
using Umbraco.Core.Services;
using Umbraco.Web.WebApi;
using System.Web.Http;

public class CardListController : UmbracoApiController
{
  public CardListController(){};
 [System.Web.Http.HttpPost]
 public JsonResult LoadMoreCards([FromBody]string page)
    {
       ....
    }

In my javascript code:

    const data = { page: '0' };
    fetch(
      `https://localhost:44378/umbraco/api/cardlist/loadmorecards/`,
      {
        method: 'POST',
        headers: {
            'Content-Type': "application/json;",
        },
        body: JSON.stringify(data) 
      }
    )

Can anyone see where this could be going wrong?
