JSON Deserialization not parsing all properties JIRA API 3

Question

I am parsing a JSON response from Jira API 3 for Change Log

I generated the response classes using json2csharp.com here's how it looks

// Root myDeserializedClass = JsonConvert.DeserializeObject<Root>(myJsonResponse);   
public class AvatarUrls  
{  
    public string _48x48 { get; set; }  
    public string _24x24 { get; set; }  
    public string _16x16 { get; set; }  
    public string _32x32 { get; set; }  
}  
  
public class Author  
{  
    public string self { get; set; }  
    public string accountId { get; set; }  
    public string emailAddress { get; set; }  
    public AvatarUrls avatarUrls { get; set; }  
    public string displayName { get; set; }  
    public bool active { get; set; }  
    public string timeZone { get; set; }  
}  
  
public class Item  
{  
    public string field { get; set; }  
    public string fieldtype { get; set; }  
    public string fieldId { get; set; }  
    public string from { get; set; }  
    public string fromString { get; set; }  
    public string to { get; set; }  
    public string toString { get; set; }  
}  
  
public class Value  
{  
    public string id { get; set; }  
    public Author author { get; set; }  
    public DateTime created { get; set; }  
    public List<Item> items { get; set; }  
}  
  
public class JsonResponseChangeLog  
{  
    public string self { get; set; }  
    public string nextPage { get; set; }  
    public int maxResults { get; set; }  
    public int startAt { get; set; }  
    public int total { get; set; }  
    public bool isLast { get; set; }  
    public List<Value> values { get; set; }  
}  

My c# code for parsing JSON response

..... HTTPClient & HttpRequestMessage objects  
var base64authorization =                               Convert.ToBase64String(Encoding.ASCII.GetBytes("" + userName + ":"+ apiToken));  
                    request.Headers.TryAddWithoutValidation("Authorization", $"Basic {base64authorization}");  
  
                    var response =  httpClient.SendAsync(request).Result;  
  
                    string responseString = null;  
                    if (response.IsSuccessStatusCode)  
                    {  
                        var responseContent = response.Content.ReadAsStringAsync().Result;  
                        var myDeserializedClass =   
                            JsonConvert.DeserializeObject<JsonResponseChangeLog>(responseContent);                            
                    }  

My result under value is always null
