[Bug]: Warning: Undefined array key "code" in Responses/FineTuning/RetrieveJobResponseError.php on line 42 about client HOT 2 OPEN

I created a PR with a fix for this issue: #363

from client.

Here is how you can create a completely new install that recreates this error. I have also included the fix

php -v

PHP 8.2.12 (cli) (built: Oct 24 2023 21:15:15) (ZTS Visual C++ 2019 x64)

Zend Engine v4.2.12, Copyright (c) Zend Technologies

composer require openai-php/client

composer dump-autoload    

nano index.php

Paste this:

<?php
require __DIR__ . '/vendor/autoload.php';

$client = OpenAI::client('insert-your-key-here');

$response = $client->fineTuning()->listJobs();
?>

php index.php

Fix:

Inside file src\Responses\FineTuning\RetrieveJobResponseError.php

Change:

private function __construct(
    public readonly string $code,
    public readonly ?string $param,
    public readonly string $message,
) {
}

To:

private function __construct(
    public readonly ?string $code,
    public readonly ?string $param,
    public readonly ?string $message,
) {
}

Change:

return new self(
    $attributes['code'],
    $attributes['param'],
    $attributes['message'],
);

To:

return new self(
    $attributes['code'] ?? null,
    $attributes['param'] ?? null,
    $attributes['message'] ?? null,
);

from client.
