Internal server error on Delete Department

[deep0892]

Livechat instead of livechat in
Rocket.Chat/packages/rocketchat-livechat/server/methods/removeDepartment.js

`Meteor.methods({
'livechat:removeDepartment'(_id) {
if (!Meteor.userId() || !RocketChat.authz.hasPermission(Meteor.userId(), 'view-livechat-manager')) {
throw new Meteor.Error('error-not-allowed', 'Not allowed', { method: 'livechat:removeDepartment' });
}

    //return RocketChat.livechat.removeDepartment(_id);
            return RocketChat.Livechat.removeDepartment(_id);
}

});`
