Illegal characters in path when calling the index view from my controller

Question

I am receiving an ArgumentException when invoking the index action of one of my controllers and I am not sure why. The error message is the following:

Server Error

Answer 1

I found it finally. It is a really embarassing typo by me. I mistyped the code:

    public ActionResult Index()
    {
        var glaccounts = db.GLAccounts.ToString();
        return View(glaccounts);
    }

instead of:

    public ActionResult Index()
    {
        var glaccounts = db.GLAccounts.ToList();
        return View(glaccounts);
    }

Then the framework wanted to load a view file, like this:

"~/Views/GLAccount/SELECT \r\n[Extent1].[Id] AS [Id], \r\n[Extent1].[OrgDefinitionId] AS [OrgDefinitionId], \r\n[Extent1].[GLAccountId] AS 
[GLAccountId], \r\n[Extent1].[Name] AS [Name], \r\n[Extent1].[StartDate] AS [StartDate], 
\r\n[Extent1].[EndDate] AS [EndDate]\r\nFROM [GLAccounts] AS [Extent1].aspx"

Hopefully, I will save couple of hours of debugging for someone else by posting this :(
