How to prevent error message after custom UI in Sitecore

I've built a content editor XML UI element. I launch it via a command with the code 

string url = Sitecore.UIUtil.GetUri("control:CloneToMarkets") + "&id=" + HttpUtility.UrlEncode(id) + "&path=" + HttpUtility.UrlEncode(path) + "&database=" + HttpUtility.UrlEncode(database);
Context.ClientPage.ClientResponse.ShowModalDialog(url, "400px", "700px", string.Empty, true);

In my DialogForm class I'm overriding OnLoad() and OnOK(). With on load I'm invoking its base method at the start of the class, and OnOk ends with the base method.

If I "ok", "cancel" or "X" on the custom DialogForm I get this error: enter image description here

My dialog works fine, and completes its purpose, I'm just getting this error afterwards. Does anyone know what causes this?

I believe that you experience a known problem when Sitecore Client users get mistakenly categorised as robots.

Usually, it happens when Sitecore Analytics is enabled and users do not visit the site front-end before logging into the Sitecore Client. In this situation, the current session may be mistakenly identified as a robot visit and will cause the admin session expiration as Sitecore Analytics reduces session timeout for robot visits aiming to minimise the server resources utilisation.

So, make sure that Sitecore.Analytics.Tracking.RobotDetection.config is disabled on your CM instance and also make the following changes in web.config:

  1. In system.web/httpModules node, name="MediaRequestSessionModule" change the following line from "Sitecore.Analytics.RobotDetection.Media.MediaRequestSessionModule, Sitecore.Analytics.RobotDetection" to "Sitecore.Analytics.Media.MediaRequestSessionModule, Sitecore.Analytics".

  2. In system.webServer/modules node, name="MediaRequestSessionModule" change the following line from "Sitecore.Analytics.RobotDetection.Media.MediaRequestSessionModule, Sitecore.Analytics.RobotDetection" to "Sitecore.Analytics.Media.MediaRequestSessionModule, Sitecore.Analytics".
