# MInor PHP bug – undeclared variable

 * Hi
 * The file `woocommerce-services/classes/class-wc-connect-functions.php` is missing
   a declaration for `$helper_auth_data` so we’re seeing the following error come
   through on our cron reports:
 *     ```wp-block-code
       Undefined variable $helper_auth_data in /web/wp-content/plugins/woocommerce-services/classes/class-wc-connect-functions.php on line 36
       ```
   
 * Can you initialise the variable before trying to reference it please?
 * Paul

 * Hi Paul,
 * Thanks for flagging this and for taking the time to report it.
 * I was able to reproduce and confirm the behavior across both versions 3.6.3 and
   3.6.2. It looks like `$helper_auth_data` should be initialized before it’s referenced
   on line 36 of class-wc-connect-functions.php, which explains the PHP warning.
 * I’m going to share this internally with the developers so they can check whether
   this is already tracked in Linear or needs logging. I’ll circle back here once
   I have an update. Hang in there
