JsonConvertDeserializeObject not working correctly

Question

I messed up somewhere and I am having some trouble with getting the JsonConvert to convert a response to my model. I am trying to call the twitch endpoint here: https://tmi.twitch.tv/group/user/CHANNEL/chatters and get the list of viewers.

Here is my code:

        {
            using var client = new HttpClient();
            var res = await client.GetAsync("https://tmi.twitch.tv/group/user/" + streamer + "/chatters").ConfigureAwait(false);
            if (res.IsSuccessStatusCode)
            {
                var str = await res.Content.ReadAsStringAsync();
                var response = JsonConvert.DeserializeObject<response>(str);
                return response;
            }
            return null;
        }```


and finally here is my model: 

public  class Response
{
    [JsonProperty("chatter_count")]
    public long ChatterCount { get; set; }

    [JsonProperty("broadcaster")]
    public string[] Broadcaster { get; set; }

    [JsonProperty("vips")]
    public string[] Vips { get; set; }

    [JsonProperty("moderators")]
    public string[] Moderators { get; set; }

    [JsonProperty("staff")]
    public object[] Staff { get; set; }

    [JsonProperty("admins")]
    public object[] Admins { get; set; }

    [JsonProperty("global_mods")]
    public object[] GlobalMods { get; set; }

    [JsonProperty("viewers")]
    public string[] Viewers { get; set; }
}

}```

Whenever I try to call my method to get the viewers I am getting App.Response with everything in the model being null even though whenever I use the same URL to in Postman or browser I get valid data back. and the

var str = ""{\n "_links": {},\n "chatter_count": 2,\n "chatters": {\n "broadcaster": [],\n "vips": [],\n
"moderators": [\n "nightbot"\n ],\n "staff": [],\n
"admins": [],\n "global_mods": [],\n "viewers": [\n
"heirmanttinan"\n ]\n }\n}\n""
