I have below query returning some json result in postgres

select t.transaction_id,
  jsonb_agg(jsonb_build_object('title', t.title, 'created_date', t.created_date, 'created_by', t.created_by))
  AS content
  from temp_table group by t.transaction_id

I have below c# code

public class MainClauseHistoryDto

{
     [JsonProperty("transaction_id")]
     public int TransactionId { get; set; }
     [JsonProperty("content")]
     public List<NegotiatedContent> NegotiatedContents { get; set; }
 }

 public class NegotiatedContent
 {
     [JsonProperty("created_by")]
     public string CreatedBy { get; set; }
     [JsonProperty("created_date")]
     public DateTime CreatedDate { get; set; }
     [JsonProperty("title")]
     public string Title{ get; set; }
 }

I would like to bind above json to NegotiatedContent. In my DataAccess layer i am calling stored procedure and returning above data as DataTable.

//below code to query db and return dataset.
    var result = await _negotiationRepository.GetMainClauseHistoryAsync(IndicationRequestId, ParagraphId);
    var mainClauseHistory = result.Tables["main_clause_history_tbl"].ToModelList<MainClauseHistoryDto>();

Below is ToModelList

public static List<T> ToModelList<T>(this DataTable dt)
{
    if(dt?.Rows.Count > 0)
    {
        var seralizeData = JsonConvert.SerializeObject(dt);
        return JsonConvert.DeserializeObject<List<T>>(seralizeData)!;
    }
    else
        return new List<T>();
}

In the above code I am getting error

Error converting value "[{"created_by": "iser1"

Above error message with whole json is coming, may I know how we can bind json directly to our c# model? Any help would be appreciated. Thanks
