Fatal error: Uncaught Error: Call to undefined method WP_Error::has_errors()

I tried to install a “NEVE” theme and got this error. Not knowing how to fix it. Please help how this can be fixed.
The goal I want to achieve is to bring back the theme I used before, namely the original WordPress theme 2017. Let me clarify that the problem happened the day before.
The places where are added dots “….” are from me.

magento2 – Magento 2 Uncaught TypeError: Constr is not a constructor when returning functions on Knockout Js

i’m trying to get functions from a JS file in a Knockou file, like this:


define(('jquery', 'uiComponent', 'ko','Vendor_GetQuote/js/ajax-request'), function ($, Component, ko, ajaxrequest) {
    'use strict';

And I try to access like this


With just one function it works, but with 2 or more it does not.

This is my ajax-request.js file

    ) {
        'use strict';

        var methods = {
            functionA: function() {
                console.log('This is from module A, functionA');
            functionB: function() {
                console.log('This is from module A, function B');
        return methods;

This is the error I’m getting:
Uncaught TypeError: Constr is not a constructor

Can someone orient me?
