Custom Payment method is not displayed on frontend

I’m stuck with creating simple payment method. It is displayed in admin panel but not on frontend.

In Chrome developer tools I get errors on frontend that are displayed on pictures below:

It seems to me, that corresponding file is not deployed into pub/static folder, though I cleared pub/static and generated directories manualy and then ran bin/magento setup:upgrade, bin/magento setup:di:compile, bin/magento setup:static-content deploy -f. And flushed cache finally.

My Payment method is just a copypasta from this source: Meetanshi Payment Method

My method-renderer.js file:

define(
[
    'uiComponent',
    'Magento_Checkout/js/model/payment/renderer-list'
],
function (
    Component,
    rendererList
) {
    'use strict';
    rendererList.push(
        {
            type: 'custompayment',
            component: 'Meetanshi_CustomPayment/js/view/payment/method-renderer/custompayment'
        }
    );
    return Component.extend({});
});

Thank You in advance!

P.S. Also I’m using custom Magento_Checkout module. Maybe this is the reason?
