 * Just to let you know that after a recent plugin upgrade we get these PHP warnings
   in our log:
 *     ```wp-block-code
       [09-Jan-2026 08:02:02 UTC] PHP Warning:  Undefined array key "PDDP" in /mysite/wp-content/plugins/dhl-for-woocommerce/includes/REST_API/Parcel_DE/Item_Info.php on line 762[09-Jan-2026 08:05:25 UTC] PHP Warning:  Undefined array key "PDDP" in /mysite/wp-content/plugins/dhl-for-woocommerce/includes/REST_API/Parcel_DE/Item_Info.php on line 762[09-Jan-2026 08:07:03 UTC] PHP Warning:  Undefined array key "PDDP" in /mysite/wp-content/plugins/dhl-for-woocommerce/includes/REST_API/Parcel_DE/Item_Info.php on line 762[09-Jan-2026 08:07:43 UTC] PHP Warning:  Undefined array key "PDDP" in /mysite/wp-content/plugins/dhl-for-woocommerce/includes/REST_API/Parcel_DE/Item_Info.php on line 762
       ```
   
 * This kind of “pollutes” our php log and makes monitoring harder.
 * Maybe you can fix the warning in an upcoming release. fwiw, I think the shop 
   does not use PDDP or at least I do not know what PDDP means at all.

 * Hi David,
   Thanks for reporting this.The warning is triggered when the optional
   PDDP flag is not present in the order data.It does not affect label creation,
   but we’ll add a safe default and include the fix in the next update.
 * Thanks for the heads-up.

 * After upgrading to the current latest plugin version we still have this in our
   logs:
 *     ```wp-block-code
       [21-May-2026 08:12:46 UTC] PHP Warning:  Undefined array key "PDDP" in /srv/data/web/vhosts/www.abc.com/htdocs/wp-content/plugins/dhl-for-woocommerce/includes/REST_API/Parcel_DE/Item_Info.php on line 762
       ```
   
 * So it is still not fixed.
