Static content deploy error after upgrading to 2.3.2

Hi!

 

After updating from 2.3.1 to 2.3.2 

running

setup:static-content:deploy

returns an error

Compilation from source: /Users/miguel/Projects/_magento/vendor/magento/theme-frontend-blank/web/css/styles-m.less

variable @color-lighter-grayish is undefined in file /Users/miguel/Projects/_magento/var/view_preprocessed/pub/static/frontend/Magento/luma/ru_RU/Magento_Checkout/css/source/module/checkout/fields/_file-uploader.less in _file-uploader.less on line 18, column 39

18| @file-uploader-preview__border-color: @color-lighter-grayish;

 

I’ve located this file in 

vendor/magento/theme-frontend-luma/Magento_Checkout/web/css/source/module/checkout/fields/_file-uploader.less 

and hardcoded 

@file-uploader-preview__border-color: #ddd; 

trying to solve the issue, but without any luck. Did anyone have similar issue after update?
