When called, this middleware renders an error page. By default if an HTML response is expected it will render static error pages from the /public
directory. For example when this middleware receives a 500 response it will render the template found in /public/500.html
. If an internationalized locale is set, this middleware will attempt to render the template in /public/500.<locale>.html
. If an internationalized template is not found it will fall back on /public/500.html
.
When a request with a content type other than HTML is made, this middleware will attempt to convert error information into the appropriate response type.
