event.player.activeEffects.forEach(effect => {

    const amp = event.entity.getEffect('bad_omen').amplifier
    event.entity.potionEffects.add('minecraft:bad_omen', 100000, amp + 1)

of course it's not defined

it needs an event

in what situation you want to increase the ampifier of bad omen

eating food?

drinking potion?

the id of food?

it's registered as a food, or potion?

send code

the code of kubejs:ominous_potion

Paste version of ominousPotionBackport.js from @steep seal

cool, then there's only one thing to do:

global.funcOminousPotionEffects = ctx => {
    const amp = ctx.player.getEffect('bad_omen').amplifier
    ctx.player.potionEffects.add('minecraft:bad_omen', 100000, amp + 1)
}

global.funcOminousPotionEffects = ctx => {
    const player = ctx.player;
    if(!player.hasEffect('minecraft:bad_omen')) {
        player.potionEffects.add('minecraft:bad_omen', 100000, 0);
        return;
    }
    const amp = player.getEffect('minecraft:bad_omen').amplifier
    player.potionEffects.add('minecraft:bad_omen', 100000, amp + 1)
}

it's null probably because the player don't have bad omen yet

if(something) {
  //then do something
}

if(!something) return //if not something, return

doesn't .useAnimation("drink") make the eating sound like potion?
a potion needs to register a new mob effect, or use extra listener

then it replaces all burp sound

nvm, let me register a mob effect

StartupEvents.registry('mob_effect', e => {
    e.create('badomen_upgrade')
        .harmful()
        .color(0x192E22)
        .effectTick((entity, level) =>{
            if(!entity || entity.level.isClientSide()) return;
            if(!entity.hasEffect('minecraft:bad_omen')) {
                entity.potionEffects.add('minecraft:bad_omen', 10000, 0);
            }
            else{
                const amp = entity.getEffect('minecraft:bad_omen').amplifier;
                entity.potionEffects.add('minecraft:bad_omen', 100000, amp + 1);
            }
            entity.removeEffect('kubejs:badomen_upgrade')
        })
})

let $PotionBuilder = Java.loadClass("dev.latvian.mods.kubejs.misc.PotionBuilder")
function potionRegist(e, id, durationInSeconds){
    e.createCustom(id, () => {
        return new $PotionBuilder(id)
        .effect(`kubejs:${id}`, durationInSeconds * 20, 0)
        .createObject()
    })
}
StartupEvents.registry("potion", e => {
    potionRegist(e, 'badomen_upgrade', 5);
})

restart the game, there should be a new potion with no translation key

and you need to add a en_us.json in kubejs/assets/lang

  "effect.kubejs.badomen_upgrade":"Bad Omen Upgrade",
  "item.minecraft.potion.effect.badomen_upgrade":"Ominous Bottle",
