Drupal 8 missing filter view schema After run unit tests i am getting fail

Schema errors for views.view.example_form_element with the following errors: views.view.example_form_element:display.default.display_options.filters.my_module.expose.example_element missing schema


I understand the error but i can't solve it. I tried a lot of combinations of schema.yml file name and content but without success result.

I will point out, that module name is 


  my_modules


but 


  example_element


is under 


  my_module


current file looks like

file config/schema/my_modules.views.schema.yml

views.filter.views_example_element:
  type: views_filter
  label: 'xxx'
  mapping:
    expose:
      type: mapping
      label: 'Exposed'
      mapping:
        example_element:
          type: integer
          label: 'xxx'


file Plugin/views/filter/ViewsExampleElement

@ViewsFilter("views_example_element")


What is wrong with it?
Try change in my_modules.views.schema.yml type on views.filter.many_to_one
