@rui.yang you should post your error log here, maybe someone can help

Re asking T_T

the exception I got is: No matching ctor found for class io.pedestal.interceptor.helpers$before$fn__6962

but in my codes, there is no direct reference to before or defbefore

but I used defhandler

which is created by calling defsimpleinterceptordef in pedestal. I am not sure if that’s the cause

using a macro to create another macro, my brain exploded 😞

i solved by remove using defhandler

using a simple macro i wrote to wrap the handler function
