Hotfixing missing array keys

What:

• Bug Fix
• New Feature

Description:

I made a small script whilst I was playing with the lib and testing the openAPi's Fine Tuning:

require_once __DIR__ . '/vendor/autoload.php';

$yourApiKey = $_ENV['OPENAI_API_KEY'];
$client = OpenAI::client($yourApiKey);

$response = $client->files()->upload([
    'purpose' => 'fine-tune',
    'file' => fopen(__DIR__.'/client_data.jsonl', 'r'),
]);

echo($response->id);

$response=$client->fineTuning()->createJob([
    'training_file' => $response->id,
    'model' => 'gpt-4o-mini-2024-07-18',
    'hyperparameters' => [
        'n_epochs' => 4,
    ]
]);

var_dump($response->toArray());

But that made the script throw the following error:

Warning: Undefined array key "code" in /usr/src/app/vendor/openai-php/client/src/Responses/FineTuning/RetrieveJobResponseError.php on line 34

Warning: Undefined array key "param" in /usr/src/app/vendor/openai-php/client/src/Responses/FineTuning/RetrieveJobResponseError.php on line 35

Warning: Undefined array key "message" in /usr/src/app/vendor/openai-php/client/src/Responses/FineTuning/RetrieveJobResponseError.php on line 36

Fatal error: Uncaught TypeError: OpenAI\Responses\FineTuning\RetrieveJobResponseError::__construct(): Argument #1 ($code) must be of type string, null given, called in /usr/src/app/vendor/openai-php/client/src/Responses/FineTuning/RetrieveJobResponseError.php on line 33 and defined in /usr/src/app/vendor/openai-php/client/src/Responses/FineTuning/RetrieveJobResponseError.php:20

Therefore in order to fix the error I made some hotfixes. It seems that happens upon a sucessfull fine-tuning submission.

Extras

The script I made needed to have the following file named client_data.jsonl and it at the same folder that also script resides to:

{"messages": [{"role": "system", "content": "Marv is a factual chatbot that is also sarcastic."}, {"role": "user", "content": "What's the capital of France?"}, {"role": "assistant", "content": "Paris, as if everyone doesn't know that already."}]}

The fix was intented as a quickfix without looking any deeper.
