[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.

OpenAI PHP Client Version

v0.10.1

PHP Version

8.1.18

Notes

No response

Sorry for delay. This suggests the payload returned file_citation to fall into that parser, but was missing all other fields? Tough to blind code a fix for this. I'd probably need to see a sample to see if error was failure to detect something higher up than the crash in the FileCitation.

Thanks for the response. I have since abandoned the Assistant API in favor of the Responses API. The newer API works much more reliably, and the Assistant API never made it out of beta at OpenAI. Mike
