Access denied to my route, created in module.routing.yml I'm having a hard time trying to figure out why my custom route is returning a 403 status.

My routing.yml file:

lightbox.content:
  path: '/lightbox/content'
  defaults:
    _controller: '\Drupal\lightbox\Controller\LightboxController::content'
    _title: 'Hello World'
    requirements:
      _permission: 'access content'
      _access: true


My permissions.yml file

access content:
  title: 'Access Content'
  description: 'Read all content'


Permission page:
The issue, as mentioned in the comment was my indentation.  I will leave this for anyone that may run into this issue.
