Error trying to apply a filter

[zanloy]

I am trying to implement a filter and I keep getting an error trying to apply the catalog.

Error message:

Error: /Stage[main]/Profiles::Sensu/Sensu::Handler[slack]/Sensu_handler[slack]/filters: change from to maint_filter failed: undefined method `sort' for nil:NilClass

Filter declaration:

sensu::filter { 'maint_filter':
  attributes => { 'maint' => 'false' },
}

Handler declaration:

sensu::handler { 'slack':
  command => 'slack.rb',
  source  => 'puppet:///modules/profiles/sensu/handlers/slack.rb',
  config  => {
    'webhook_url' => '***FILTERED**',
    'channel'     => '#sensu',
  },
  mutator => 'maint_mode',
  filters => ['maint_filter'],
}

Any help would be greatly appreciated.
