Missing route message for routes with periods

[brianfreytag]

I'm running into an issue where my project is not able to follow routes that use a period syntax.

/**
 * @Route("/my/page/so-good", name="my.page.so_good")
 */
public function soGoodAction(Request $request)
{
    ...
}

return $this->redirect($this->generateUrl('my.page.so_good'); 

On the generateUrl() I am receiving a Missing Route error, even within the same file and within the same method, however, an underscore syntax would work my_page_so_good but we prefer to use a period syntax in our project route names.
