Request Headers Meta information for 'x-request-id'

[rodrigoisabelo]

Overview:
We have created an API Service indentical with OpenAI API deployed on a server from a third-party company. The payload and response is at most identical to OpenAI but I think it differs on the headers.

Steps

1. On creating the OpenAI Client, we replaced the base uri with our custom API endpoint
2. Tried sending a chat completion streaming request to it
3. I got an exception around this line #L31C58-L31C58

Exception

Initial Investigation:

1. MetaInformation class first parameter is optional, this means there should be no problem
2. Upon receiving the response, meta information is instantiated through the array form of OpenAI Response

   client/src/ValueObjects/Transporter/Response.php

   Lines 35 to 41 in 1287f56

   	public static function from(array|string $data, array $headers): self
   	{
   	// @phpstan-ignore-next-line
   	$meta = MetaInformation::from($headers);
   	return new self($data, $meta);
   	}

3. Line #L31C58-L31C58 should handle of whether the array headers have key x-request-id or not in addition to null check.

   client/src/Responses/Meta/MetaInformation.php

   Line 31 in 1287f56

   $requestId = $headers['x-request-id'][0] ?? null;

I'm trying to use this with https://github.com/h2oai/h2ogpt and getting the same error. How did you solve this ?
