ejabberd mod_rest installation warning & crash report - ejabberd

Question

I've tried to test mod_rest for my ejabberd. Received 'OK' result but with warning : "Warning: undefined callback function depends/2 (behaviour 'gen_mod')" during installation of the module. When I tried to test mod_rest that I installed using REST client, there's CRASH REPORT in log.
