Hi@apc-harold

I am not able to reproduce the issue. When I upload a file, the filename is set properly.

Could you please provided a full example or a demo repository which reproduces the issue?

Hi@gehrisandro,

Thanks for checking it out!

I'm quite busy at the moment so won't be able to provide an example, but:

• Using Laravel, using $file->get() to retrieve the file
• Using thebeta version

I'll maybe have some time on w/s 17th, so will make a reminder to come back and make an example if it's still here.

I stumbled on the same problem:
it is not easily possible to upload string data as a file, because no filename (or an invalid filename) gets sent that is missing the ".jsonl" extension.

This may also be remedied by adding the following code to the file upload example:

$jsonlData ="{...}\n{...}";$response =$client->files()->upload(['purpose' =>'fine-tune','file' => \GuzzleHttp\Psr7\Utils::streamFor($jsonlData, ["metadata" => ["uri" =>"upload.jsonl"]]),    ]);

@DennisBirkholz thanks! Works for me. I'm using the Laravel driver and was stuck in how properly handle this uploads.
