I am needing to redirect a user to a specific page after they have logged in and I know what type of user they are based on custom profile settings we have. The hook for ILoginCompletedEvent is working fine. I get to the LoginCompletedEventVerification method when I would expect to. The custom profile part "PTL_Extensions.Security.IsClient(userIDGuid)" is working fine. The redirect is where I need some assistance.

I have found and followed the guidance given in the following two articles:

HOW TO REDIRECT TO SPECIFIC PAGE UPON LOGIN

https://knowledgebase.progress.com/articles/Article/How-to-redirect-to-specific-page-upon-login

and

ILoginCompletedEvent FOR DEVELOPERS

https://www.progress.com/documentation/sitefinity-cms/for-developers-ilogincompletedevent

My LoginCompletedEventVerification method is as follows:

private void LoginCompletedEventVerification(ILoginCompletedEvent evt)
{
if (evt.LoginResult == UserLoggingReason.Success)
{
var userName = evt.Username;
var userEmail = evt.Email;
var userIDGuid = Guid.Parse(evt.UserId);
var userIP = evt.IpAddress;

//if (!PTL_Extensions.Security.IsEmployee(currentUser.Id))
if (PTL_Extensions.Security.IsEmployee(userIDGuid))
{
// redirect to Legacy Premier iFrame page
Response.Redirect("/my-premier/my-premier-legacy");
}
else if (PTL_Extensions.Security.IsClient(userIDGuid))
{
// redirect to Client Dashboard
Response.Redirect("/my-premier/customer-dashboard");

}
else
{
//redirect to Home Page
}

}

If I uncomment the Response.Redirect("/my-premier/customer-dashboard"); lines, I get the following exception:

Server Error in '/' Application.
