Hey, @jibiking

skip_bugsnag works on the specific instance of the exception you apply it to. In your example you're applying it to exception but raising a RoutingError afterwards. That means that the RoutingError doesn't have skip_bugsnag applied to it, which results in it being reported to Bugsnag

To make it work you'd need to apply skip_bugsnag to the RoutingError before raising it, like this:

begin
  raise StandardError
rescue StandardError => exception
  Bugsnag.notify(exception)

  routing_error = ActionController::RoutingError.new('not_found')
  routing_error.instance_eval { def skip_bugsnag; true; end }

  raise routing_error
end

If you want to ignore all RoutingError exceptions, take a look at the discard_classes configuration option

Hope that helps!
