[Bug]: Fail gracefully on unsuccessful request

[NoxArt]

Description

If the request fails, this line will simply crash on "Call to a member function getBody() on null" instead of handling this usecase somehow - at least to convert it to a semantic exception e.g. RequestFailedException or something

Thank you

Steps To Reproduce

Make a request that will somehow fail, maybe towards non-existing endpoint?

For us it fails during Files->Download

It may be related to response "The server had an error processing your request. Sorry about that! You can retry your request, or contact us through our help center at help.openai.co..."

OpenAI PHP Client Version

v0.10.1

PHP Version

8.1.27

Notes

No response

Btw there are similar failures:

OpenAI\Responses\Batches\BatchResponse::__construct(): Argument #1 ($id) must be of type string, null given

OpenAI\ValueObjects\Transporter\Response::from(): Argument #1 ($data) must be of type array|string, null given

...

The library generates many generic errors that is not easy to handle nicely

Hi @NoxArt

Feel free to submit a PR to improve the error handling.
