The integration with k2 is very outdated. I gave up on renaming the equipment categories, and before that, there were settings, weapon names, and fuel subgroups.

Managed to (sorta?) fix this error and get the mod working with K2 and SE. Hanuryk got the right idea about renaming the outdated parts of the code. Here is the changes I made in the lua files:

data-updates:

if mods["Krastorio2"] then
require("prototypes.k2items")
data.raw["spider-vehicle"]["lex-flying-cargo"].energy_source.fuel_categories = { "kr-vehicle-fuel" }
data.raw["spider-vehicle"]["lex-flying-gunship"].energy_source.fuel_categories = { "kr-vehicle-fuel" }
data.raw["spider-vehicle"]["lex-flying-heavyship"].energy_source.fuel_categories = { "kr-vehicle-fuel" }
data.raw["equipment-grid"]["lex-flying-cargo-grid"].equipment_categories = {
"kr-vehicle",
"kr-vehicle-motor",
"kr-vehicle-roboport",
}
data.raw["equipment-grid"]["lex-flying-gunship-grid"].equipment_categories = {
"kr-vehicle",
"kr-vehicle-motor",
"kr-vehicle-roboport",
}
data.raw["equipment-grid"]["lex-flying-heavyship-grid"].equipment_categories = {
"kr-vehicle",
"kr-vehicle-motor",
"kr-vehicle-roboport",
}
data.raw["equipment-grid"]["lex-flying-heavyship-grid"].equipment_categories = {
"kr-vehicle",
"kr-vehicle-motor",
"kr-vehicle-roboport",
}
table.insert(data.raw["spider-vehicle"]["lex-flying-heavyship"].guns, "rocket-launcher")
if settings.startup["kr-realistic-weapons"].value then
table.insert(data.raw["spider-vehicle"]["lex-flying-heavyship"].guns, "lex-advanced-machine-gun")

k2items.lua:

if mods["Krastorio2"] and settings.startup["kr-realistic-weapons"].value then
data:extend({
{
type = "gun",
name = "lex-advanced-machine-gun",
icon = "Krastorio2Assets/icons/guns/advanced-tank-machine-gun.png",
icon_size = 64,
hidden = true,
subgroup = "gun",
order = "z[tank]-a[advanced-tank-machine-gun]",
attack_parameters = {
type = "projectile",
ammo_category = "kr-anti-materiel-rifle-ammo",
