hi guys, how can I handle authentication using JWT in a HTTP header? I've taken a little dive into the source code and tried providing a custom :verify handler in the :access-control map but got a cryptic error about not being able to create the resource, something like :error :access-control :realm "default" not (namespace :verify) (don't remember which bracket goes where)

It means that you're trying to put the verify function at the wrong level

yada only expects a certain set of unqualified keywords at each level of the map

you'll need to show the full error, also helpful is to show the ex-data for the exception

Am I looking at :exists? correctly in the issue above, or am I misunderstanding what it's for?

It is for allowing properties to sat that a resource doesn't exist so the response fn doesn't need to be called at.

all

A PUT to a resource that doesn't exist is quite valid.

As is a POST

But a GET would be 404

Depends on the method's semantics

So if I want to return 404 to a PUT, then I need to return it myself?

Fair enough

Yes

Yada can't know what your intent is.

It has to call your response function when the semantics of the method are undefined.
