Here is part of the script for use with the new 1.12.2 to add back in the old shapeless crafting but when the script loads i get errors saying that it cant find the given objects

am i using the wrong meta data for the bags to add them to the shapeless crafting and or how will i find the correct ones to be able to make a working script
//LootBags
recipes.addshapeless(lootbags:lootbag:1,[lootbags:lootbag * 4]);
recipes.addshapeless(lootbags:lootbag:2,[lootbags:lootbag:1 * 4]);
recipes.addshapeless(lootbags:lootbag:3,[lootbags:lootbag:2 * 4]);
recipes.addshapeless(lootbags:lootbag:4,[lootbags:lootbag:3 * 4]);

Here are my config files just in case you need them
lootbagconfigfiles.zip

Dunno how I missed this issue, hopefully you solved it yourself.
I have no idea how to use that scripting system, but assuming the format is modid:itemname:metadata, then the metadatas are all wrong, the Lootbags_BagConfig.cfg file will have the itemnames for each specific bag under the $STARTBAG command.
