Resend invoice from Admin is not working

[antonioperic]

Resend invoice is not working, the reason is because RedirectResponse is used, so event which should fire sending email is never executed.

adding event dispatcher to action, and adding this line before return RedirectResponse will fix the issue. I don't know is there any more elegant solution

$this->eventDispatcher->addListener('kernel.terminate', function(){});
