calling API data in Blazor WebAssembly in .NET 6.0

Question

{
    public int menuID { get; set; }
    public string menuTitle { get; set; }
    public int menuINDEX { get; set; }
    public bool menuAcitve { get; set; }
    public int menuLevel { get; set; }
    public int menuGroupID { get; set; }
    public string menuURL { get; set; }

i want to get data from using REST API but failed to get data i have used the following method

     public async  Task<IEnumerable<TblMenus>>Getoutput()
    {
       
        //https://liveexshield.com/apiBLZ/api/GETData/2,a,a
         return await 
         httpClient.GetFromJsonAsync<TblMenus[]>"apiBLZ/api/GETData/2,a,a");
      
    }

but when i use another api to get data same mehtod works fine but in this case my api is working
