Description
The return value of the
errorResponseconfig option function gets passed directly toreply.sendand as such can support a wide range of possible values. Since the documentation encourages using this option to supply one's own error shape, it shouldn't make assumptions about the type, so I've set it tounknownin order to fix the type error I get when supplying my own error shape.
