Unable to create Shadowlands/Dragonflight items in store

[DevGamX]

I am unable to create a Shadowlands or Dragonflight item in the Store, I have this error message:

==> Severity: Warning --> Trying to access array offset on value of type bool E:\Wamp64\www\mysite\application\emulators\trinity_rbac_sl_soap.php 476

Here is Favorit's interim solution which I thank because now I will be able to add 9.2 and 10 objects. Here is the request:

INSERT INTO store_items (id, itemid, name, quality, vp_price, dp_price, realm, description, icon, group, query, query_database, query_need_character, command, command_need_character, require_character_offline, tooltip) VALUES (156, '166509', 'Abyss Phoenix', 5, 150, 25, 1, NULL, 'inv_misc_gift_03', 4, NULL, '', 0, '.send items {CHARACTER} "Heron Store" "You got some mount" 166509', 1, 0, 0);

And I was even able to send it into the game.
