Argument 3 passed to Symfony\Component\HttpKernel\Exception\ServiceUnavailableHttpException::__construct() must be an instance of Exception or null, array given

I agree this is needed. +1 for the approach in #6.

To reproduce this error you need to have code that calls \Drupal\fast404\Fast404::response() without passing TRUE as an argument. This appears to only happen in fast404_preboot(), so to see this you probably have to be using the advanced installation which entails modifying your settings.php to call fast404_preboot(). If you've done that, then you will hit this error every time fast404 returns a 404.

Uploading patch that resolves this for the 3.x branch.
