Fellow Perl Monks, I pray for your wisdom

I want to write a slack bot which will perform certain services for me, however, I can't even get the most basic example (the one from the module) to work.

I installed Bot::Backbone::Service::SlackChat, and copied the example verbatim, except for putting in my own API key, which I got from slack.

package EzopBot;
use Bot::Backbone;

service slack_chat => (
    service => 'SlackChat',
        token   => 'xoxb-297...etc...', # see slack.com for your token
+s                                                                    
+                                                 
        );

service dice => (
    service => 'OFun::Dice',
    );

service "general_chat" =>
  (
   service    => 'GroupChat',
   chat       => 'SlackChat',
   group      => 'C',
   dispatcher => 'general_dispatch',
  );

dispatcher 'general_dispatch' => as {
    redispatch_to "dice";
    };

__PACKAGE__->new->run;

When I try to run this code, all I get back is no such chat as SlackChat

If I try to step through code, I can see that the SlackChat service seems allocated:

so I conclude the driver routines get loaded, and something else is going wonky.

Would be grateful for any clues
