PHP Interface Phly\Conduit\ErrorMiddlewareInterface
Error middleware is essentially the same as the
MiddlewareInterface, with
one key distinction: it has an additional argument prepended, representing
an error condition.
Next will skip error middleware if called without an error; conversely,
if called with an error, it will skip normal middleware.
Error middleware does something with the arguments passed, and then
either returns a response, or calls
$out, with or without the error.
