I will look into if we can run it via the base class when iteration is finished, otherwise we will have to add this task on the providers until 2.0.0 </p></blockquote> <h4 id="summary-steps-reproduce">Steps to reproduce</h4> <p>- Enable AI CKEditor integration module + AI Provider OpenAI<br> - Add AI button to CKEditor<br> - Enable "Fix spelling" for example<br> - Select a text in CKEditor that needs spelling fixes.<br> - The action gets performed, but the debugger never enters the method `\Drupal\ai\OperationType\Chat\StreamedChatMessageIterator::triggerEvent`</p> <h3 id="summary-proposed-resolution">Proposed resolution</h3> <p>Feedback by Marcus Johansson:</p> <blockquote><p>__destruct magic method would most likely work to trigger it</p></blockquote> > Related issue: [Issue #3524435](https://www.drupal.org/node/3524435) > Related issue: [Issue #3517618](https://www.drupal.org/node/3517618)
