a bit more info - I can see the widget opened event is sent to the chatbot, and I can see in my logs that it "hears" the "widgetOpened" event. But, there is no response returned to the widget. (in my chrome browser, I can see the request sent, but there is no response.)
Here's my botman.php route:
$botman = resolve('botman');
$botman->on('widgetOpened', function($payload, $bot) {
Log::info('botman route: heard opened event');
$bot->reply('test');
});
