I have the following problem.

when I use the define , I have the error " core not defined"  and all the dependencies too.

I add [] because , i have error " Dependencies should be defined by an array: function(require)"

Example: 

odoo.define('pos_button.Custom', [], function (require) {
"use strict";
var core = require('web.Core');

i try 
 odoo.define('pos_button.Custom',[], function(require) {

    'use strict';

      const { Gui } = require('point_of_sale.Gui');

      const PosComponent = require('point_of_sale.PosComponent');

      const { identifyError } = require('point_of_sale.utils');

      const ProductScreen = require('point_of_sale.ProductScreen');

      const { useListener } = require("@web/core/utils/hooks");

      const Registries = require('point_of_sale.Registries');

      const PaymentScreen = require('point_of_sale.PaymentScreen');

      console.log("Custom JavaScript In POS")

but i have error "TypeError: require(...) is undefined"

What am I doing wrong?

Thanks for help.
