Notice : undefined $endpoints

Hi there,
First of all tank you for your nice work!
Is it just me or there is now a notice & a warning generated by the plugin:
Notice: Undefined variable: endpoints in ...../plugins/rest-api-toolbox/includes/settings/class-rest-api-toolbox-settings-custom-post-types.php on line 47
Warning: Invalid argument supplied for foreach() in ...../plugins/rest-api-toolbox/includes/settings/class-rest-api-toolbox-settings-custom-post-types.php on line 47
