<h3 id="summary-problem-motivation">Problem/Motivation</h3>
<p>responseToArray() fails with uninitialized properties: The responseToArray() method calls getter methods on the Partitech\PhpMistral\Clients\Response object without checking if<br>
properties are initialized. For example, $response->getPages() throws an error when the $pages property is not set (which is the case for non-document chat responses). </p>
