anyone around? I'm having some trouble getting custom auth to work with yada

what is the problem?

Trying to figure out how custom authorization works. Following the sample from chapter 11.4 in Yada manual we tried the following

But calling that GET resource fails with this error

java.lang.AssertionError: Assert failed: (:method-wrapper ctx)
	at yada.interceptors$invoke_method.invokeStatic(interceptors.clj:341)
	at yada.interceptors$invoke_method.invoke(interceptors.clj:337) 

Trying to see whats wrong in this resource definition. Greatly appreciate any help on this... thx.
