KubeJs custom recipe create integration not working

[ToddynhoVT9]

one of the KubeJs scripts integration with create (1605.1.4-build.12) is giving error even using an example from https://mods.latvian.dev/books/kubejs/page/kubejs-create I'm in version 1.16. 5 of minecraft here is the script that is not working:

onEvent('recipe', evente => {
event.recipe.create.mixing(fluid.of('dustrial_decor:rusty_iron_ingot', 500), [
fluid.of('water', 100),
'minecraft:iron_ingot'
]).heated()
})

example I used:

onEvent('recipe', evente => {
event.recipes.create.mixing(Fluid.of('create:builders_tea',500),[
Fluid.of('milk',250),
Fluid.of('water',250),
'#leaves'
]).heated()

if anyone knows how to solve or what is causing the problem please tell me :)
