How to find why Exception of type 'System.Web.HttpUnhandledException' was thrown

I am not very familier with Windows servers and I was asked to put asp.net app and new windows server. As the app owner could not provide any documentation, I manage to set it up where I am stack at Exception error. The app page is just white screen and I get this error:

w3wp.exe Error: 0 :  <19.09.2023 06:26:52> System.Web.HttpUnhandledException (0x80004005): Exception of type 'System.Web.HttpUnhandledException' was thrown. ---> System.Reflection.TargetParameterCountException: Parameter count mismatch.

   at System.Web.HttpApplication.ExecuteStepImpl(IExecutionStep step)
   at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)

I understand that I need to check InnerException but how to access it, if I don't know nothing about this app's code.

Add below line of code to error message:-

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

The InnerException property will give you more details about your error.

I hope it helps!
