Hello Magento Friends,

Today I am here with a very important and useful Magento solution for you. How to Solve Issue of TypeError: Unable to Process Binding renderReCaptcha in Magento 2.4.3 and Magento 2.4.3-P1.

When you upgrade to Magento 2.4.3, the JS Knockout throws the following error on the checkout.

When you have disabled the Magento CAPTCHA on the storefront, this error occurs. Let us know how to solve the issue of RECAPTCHA on the checkout page.

Step 1: Create requirejs-config.js in the below path

Now add the code as follows

var config = {
    config: {
        mixins: {
            'Magento_ReCaptchaFrontendUi/js/reCaptcha': {
                'Vendor_Extension/js/recaptcha-mixin': true
            }
        }
    }
};

And add the below code

define([
    'uiComponent',
    'jquery',
    'ko',

    'Magento_ReCaptchaFrontendUi/js/reCaptchaScriptLoader',
    'Magento_ReCaptchaFrontendUi/js/nonInlineReCaptchaRenderer'
], function(Component, $, ko, _, registry, reCaptchaLoader, nonInlineReCaptchaRenderer) {
    'use strict';

    return function(Component) {
        return Component.extend({
            initCaptcha: function () {
               //here is check for RECAPTCHA settings
                if (typeof this.settings === 'undefined')
                {
                    return;
                }
                          
                var $parentForm,
                    $wrapper,
                    $reCaptcha,
                    widgetId,
                    parameters;

                if (this.captchaInitialized)
                {
                    return;
                }

                this.captchaInitialized = true;
                             
                $wrapper = $('#' + this.getReCaptchaId() + '-wrapper');
                $reCaptcha = $wrapper.find('.g-recaptcha');
                $reCaptcha.attr('id', this.getReCaptchaId());

                $parentForm = $wrapper.parents('form');

                parameters = _.extend(
                    {
                        'callback': function (token) { // jscs:ignore jsDoc
                            this.reCaptchaCallback(token);
                            this.validateReCaptcha(true);
                        }.bind(this),
                        'expired-callback': function () {
                            this.validateReCaptcha(false);
                        }.bind(this)
                    },
                    this.settings.rendering
                );

                if (parameters.size === 'invisible' && parameters.badge !== 'inline')
                {
                    nonInlineReCaptchaRenderer.add($reCaptcha, parameters);
                }

                
                widgetId = grecaptcha.render(this.getReCaptchaId(), parameters);
                this.initParentForm($parentForm, widgetId);

                registry.ids.push(this.getReCaptchaId());
                registry.captchaList.push(widgetId);
                registry.tokenFields.push(this.tokenField);
            },

            getIsInvisibleRecaptcha: function ()
            {
                // checking getIsInvisibleRecaptcha  settings
                if (typeof this.settings === 'undefined')
                {
                    return;
                }              
                return this.settings.invisible;
