[Bug]: Undefined array keys in ThreadMessageResponseContentTextAnnotationFileCitationObject.php

[mmcgowan1]

Description

Periodically, undefined array keys "start_index", "end_index", and "file_citation" produce a fatal error:

Uncaught TypeError: OpenAI\Responses\Threads\Messages\ThreadMessageResponseContentTextAnnotationFileCitation::from(): Argument #1 ($attributes) must be of type array, null given

Steps To Reproduce

The fatal error occurs unpredictably while streaming a response from an Assistant. Retrying the same query will not generate the error a second time. There can be dozens of queries between fatal erros.
