Found bug in Magento 2.2.6 (maybe can be reproduced in early versions).
Magento uses the same
Magento\Cms\Ui\Component\DataProvider
class for both components cms_block_listing.xml, cms_page_listing.xml
When admin user has access in cms_block & NOT cms_page throws exception
{"0":"The configuration parameter \"componentType\" is a required for \"cms_page_columns\" component.","1":"#0
