for some reason it seams like some core js functions arent loaded until the start up script for some reason,
is this intended or am i doing something wrong?
Log:
[09:49:18] [ERROR] ! generate.js#45: Error in 'StartupEvents.registry': TypeError: Cannot find function concacat in object literal{Iron fishing scroll}[style={color=#A5DEFF}].
(the rest is just info stuff)

im having the same issue as before @smoky gate

#

even when spelled correctly or at least i think it is

#

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/concat

MDN Web Docs

Array.prototype.concat() - JavaScript | MDN

The concat() method of Array instances is used to merge two or more arrays.
This method does not change the existing arrays, but instead returns a new array.

#

and mozilla says yes you can do concat with arrays

#

ye

light junco Funi block lol

you can pretty much just ignore the upper part thats just the input for generating a bunch of items :p

smoky gate Mar 30, 2026, 8:33 AM

#

unkempt drift ye

i have not looked at your code but there's a chance Rhino doesn't like concat?

#

random ass guess, maybe try using concat in a simple logging instruction and see if that cries

light junco Mar 30, 2026, 8:33 AM

#

Just copy paste the example into kjs and see if it errors

xd big modpack give it a second

unkempt drift Mar 30, 2026, 8:37 AM

#

smoky gate i have not looked at your code but there's a chance Rhino doesn't like concat?

i mean possible but i fought kube js supported all core js functions

unkempt drift Mar 30, 2026, 8:37 AM

#

light junco Hawooooo

eyyyyyyy

#

i woke up at 4 am today ^^

#

so ah xd i may make some stupid mistakes

light junco Mar 30, 2026, 8:38 AM

#

unkempt drift xd big modpack give it a second

For testing stuff like this just do /kubejs reload server_scripts and it's instant :P

unkempt drift Mar 30, 2026, 8:39 AM

#

ah ye true i could just comment out the start up script

light junco Mar 30, 2026, 8:40 AM

hmmm

#

This is why I always had separate kjs-only instances :P

unkempt drift Mar 30, 2026, 8:47 AM

#

xd thatssssssssssss

#

a actually really good idea

#

ah but then some scripts require mods for recipe and tags and stuff

#

but ye i could make like a min modpack version with only the mods that my kube js scripts use

light junco Mar 30, 2026, 8:51 AM

#

I used to keep it minimal and use placeholder vanilla items for recipes, then replace them when put back into the pack
