As a first step, that assumption has to be fixed and as a second step a new API should be introduced in a follow up issue (<span class="drupalorg-gitlab-issue-link drupalorg-gitlab-link-wrapper"><a href="https://git.drupalcode.org/project/ai_search/-/work_items/3579758" class="drupalorg-gitlab-link">https://git.drupalcode.org/project/ai_search/-/work_items/3579758</a></span>) for running access checks on other types of indexed data.</p> <h4 id="summary-steps-reproduce">Steps to reproduce</h4> <h3 id="summary-proposed-resolution">Proposed resolution</h3> <p>Removed hardcoded expectation from the code that only content entities can be indexed.</p> <h3 id="summary-remaining-tasks">Remaining tasks</h3> <h3 id="summary-ui-changes">User interface changes</h3> <h3 id="summary-api-changes">API changes</h3> <h3 id="summary-data-model-changes">Data model changes</h3> > Related issue: [Issue #3575992](https://www.drupal.org/node/3575992)
