How to find why I get an "Exception of type" System.Web.HttpUnhandledException "selected?"

I get

System.Web.HttpException
Error executing child request for handler 'System.Web.Mvc.HttpHandlerUtil+ServerExecuteHttpHandlerWrapper'.
Stack is
at System.Web.HttpServerUtility.ExecuteInternal(IHttpHandler handler, TextWriter writer, Boolean preserveForm, Boolean setPreviousPage, VirtualPath path, VirtualPath filePath, String physPath, Exception error, String queryStringOverride)

at System.Web.Mvc.ControllerActionInvoker.InvokeActionResultWithFilters(ControllerContext controllerContext, IList`1 filters, ActionResult actionResult)
at System.Web.Mvc.ControllerActionInvoker.InvokeAction(ControllerContext controllerContext, String actionName)

and internal exception

System.Web.HttpUnhandledException

I saw similar material in many other issues and usually there is a more or less clear message from which the problem can be deduced.

In my case, just Exception of type 'System.Web.HttpUnhandledException' was thrown.

How to extract additional information from this HttpUnhandledExceptionto try to find out why it was thrown?

It turns out my code did not extract InnerExceptionthis HttpUnhandledException. I captured IIS sources (yes, they can be officially downloaded) and found that System.Web.UI.Page.HandleError(Exception e)throws HttpUnhandledExceptionand passes eto my constructor. I expect that InnerExceptionof HttpUnhandledExceptionwill prove useful.

:

errorMessage += "\n\n Inner Exception:\n\n" +ex.InnerException;

InnerException .
