Error views/endpoints are Mustache files prefixed with "⚡️". They support Mustache layouts, however beyond layouts they are very restricted. For example you may not load data into a Mustache error view.
Multiple error views may be defined. The nearest error view to the endpoint causing the error
will be served. For example, given an endpoint generating an error at
the error view
/here/⚡️.html will be served instead of the earlier error view at
Default / Catch-All
The default error view used when a more specific error view is not defined is called
Naming the error view
⚡️NotFound.html will cause this to be selected
over the default error view in cases that are "Not Found-Like". This includes simple
missing endpoints, as well as uncaught cases where a loaded Model was not found.
