doesn't respect the nbt in input

[partglm]

hello i have a code but it do the recipe and forgot the nbt so i can't do a recipe with a specific nbt in input

  const withNBT = (item, stage) => {
       return { 
           item: item, 
           nbt: `{etapeOfProcess:${stage}}`
       };
   };

   // Étape 2 : Mixing avec sulfuric_acid
   event.custom({
       "type": "create:mixing",
       "results": [withNBT("kubejs:cu_item_10", 2)],
       "ingredients": [
           { "fluid": "mekanism:sulfuric_acid", "amount": 1000 },
           { "item": "mekaevolution:cosmic_control_circuit" }
       ],
       "heatRequirement": "superheated"
   });

   // Étape 3 : Mixing avec hydrofluoric_acid
   event.custom({
       "type": "create:mixing",
       "results": [withNBT("kubejs:cu_item_10", 3)],
       "ingredients": [
           { "fluid": "mekanism:hydrofluoric_acid", "amount": 1000 },
           withNBT("kubejs:cu_item_10", 2) // Nécessite étape 2
       ],
       "heatRequirement": "superheated"
   });
