Error "Cannot read property 'indexedOptions' " when removing Company field (Remove checkout field)

Question

I need to remove Company field from checkout page. I am trying to follow this tutorials "Remove a component". But I am getting next Error:

Uncaught TypeError: Cannot read property 'indexedOptions' of undefined(…) region.js:59 

My Plugins file is:

public function aroundProcess(\Magento\Checkout\Block\Checkout\LayoutProcessor $subject, \Closure $proceed, $jsLayout) {
    unset($jsLayout['components']['checkout']['children']['steps']['children']['shipping-step']
            ['children']['shippingAddress']['children']['shipping-address-fieldset']['children']['company']);
    return $jsLayout;
}

Can anyone explain me please what i am doing wrong?

Answer 1

I found the solution in this page https://github.com/magento/magento2/issues/4425

And the working code is:

public function aroundProcess(\Magento\Checkout\Block\Checkout\LayoutProcessor $subject, \Closure $proceed, $jsLayout) {
    $ret = $proceed($jsLayout);
    unset($ret['components']['checkout']['children']['steps']['children']['shipping-step']
            ['children']['shippingAddress']['children']['shipping-address-fieldset']['children']['company']);
    return $ret;
}

From this plugin documentation I found also the problem: "It is also worth noting that you are responsible for forwarding the arguments from the plugin to the proceed callable." I add the the plugin function signature from @Aaron Allen answer to my previous post so it would be more clearer to anyone who would be needing it.

function aroundMethod ($subject, \Closure $proceed, $arg1, $arg2, etc...)
