Major PageCache Issue

Created on 11 June 2025, 22 days ago

Problem/Motivation

By setting static::ALLOW in the HeadlessPreviewRequestPolicy class, the entire page cache of the Drupal install is impacted, because this essentially forcefully enables page cache for all NON-Preview Routes.

Steps to reproduce

Install the headless cms preview module and watch the backend break.

Proposed resolution

Return NULL instead of ALLOW in the policy.
