# Undefined array key “rest_route”

 * Hello,
 * I’m seeing a PHP warning to the PHP log when browsing the admin of a site.
 *     ```wp-block-code
       PHP message: PHP Warning: Undefined array key "rest_route" in .../public/wp-content/plugins/stellarpay/src/Integrations/WooCommerce/FeatureSupport/ReactBasedPaymentSettings.php on line 114
       ```
   
 * Checking the source within the `isWoocommerceAdminPaymentsProviderRestApiRequest()`
   function on line 110, there’s an assumption that `$GLOBALS['wp']->query_vars['
   rest_route']` exists on line 114.
 * Above this line, there is a check of:
 *     ```wp-block-code
       if (!WC()->is_rest_api_request()) {    return false;}
       ```
   
 * Can this be expanded to also check the variable exists? e.g.
 *     ```wp-block-code
       if (!WC()->is_rest_api_request() || empty( $GLOBALS['wp']->query_vars['rest_route'] )) {    return false;}
       ```
