Entity queries must explicitly set whether the query should be access checked or not.

Problem/Motivation

If you try to reindex the backlinks in admin/config/content/backlinks there's a php error:

Drupal\Core\Entity\Query\QueryException: Entity queries must explicitly set whether the query should be access checked or not. See Drupal\Core\Entity\Query\QueryInterface::accessCheck(). in Drupal\Core\Entity\Query\Sql\Query->prepare() (regel 141 van web/core/lib/Drupal/Core/Entity/Query/Sql/Query.php).

Access checking must be explicitly specified on content entity queries.

Steps to reproduce

1. Go to admin/config/content/backlinks
2. Check some content types
3. Hit re-index button

Proposed resolution

Add ->accessCheck(FALSE) to query's in BacklinksScanBatch.php

Remaining tasks

Create MR (i'll try to fix it today but last hours before vacation).
