Internal error during incident update via RestAPI in C#

Hello,

I'm trying to update an incident via RestAPI within my C# application, but i get an error message: {"status":500,"message":"null"}

Below you can see what code i use

public void saUpdateTicket(string saTicket, string TDTicket)
        {
            string someUser = "********";
            string someAccount = "*******";
            string somePass = "*********";
            SysaidUpdate saUpdate = new SysaidUpdate();
            saUpdate.id = saTicket;
            var objLogin = new Login(someUser, someAccount, somePass);

var client = new RestClient("https://<SERVER>:8443/api/v1");

var loginRequest = new RestRequest("login", Method.POST);
            loginRequest.AddJsonBody(objLogin);
            var responseLogin = client.Execute(loginRequest);

client.CookieContainer = new System.Net.CookieContainer();
            var authCookie = responseLogin.Cookies.First(a => a.Name == "JSESSIONID");
            client.CookieContainer.Add(new System.Net.Cookie(authCookie.Name, authCookie.Value, authCookie.Path, authCookie.Domain));

List<saUpdateInfo> saInfo = new List<saUpdateInfo>();
            saInfo.Add(new saUpdateInfo { key = "CustomColumn3sr", value = TDTicket});
            saUpdate.info = saInfo;

string json = JsonConvert.SerializeObject(saUpdate);
            StringContent content = new StringContent(json, Encoding.UTF8, "application/json");
       
            string input = @"/" + saTicket;

var getUserRequest = new RestRequest($"sr{input}", Method.PUT);
            getUserRequest.AddJsonBody(content);
            var result = client.Execute(getUserRequest);

string r = result.Content.ToString();

}

Any help would be great.

Thanks in advance.
