[Plugin: Swiftype Search] undefined class action

Hello

After enabling the debug mode on wordpress appeared the following Notice: Undefined index: action in …\wp-content\plugins\swiftype-search\class-swiftype-plugin.php on line 3 – line 8 – line 11 and line 14

Is just a notice, but if they could fix it, thanks
