mod_rest on ejabberd 15.0.4 on MAC OS X yosemite is not starting

Question

I have been trying to configure mod_rest in my ejabberd(ver 15.0.4) server to connect it with http server(XAMPP) but after compiling and setting everything it won't get started and generates a crash reports.

mod_rest.erl is downloaded from: https://github.com/processone/ejabberd-contrib/tree/master/mod_rest

Configration settings used in yml :

 mod_rest: []
 - 
    port: 5285
    module: ejabberd_http
    request_handlers:
       "/rest": mod_rest

Answer 1

I think it means you should also start the module from the modules section as well.
