It should not be possible in theory for something to work in postman and not when running from the code, if they are in fact the same, so something has to be up here. It's hard to debug this way, but as a shot in the dark

1/ Enable logging and check if any errors get recorded?
2/ Why is the file name in the path pngwing.com (1).png and then in the filename param it is test.png
3/ Test with a file that does not have a space nor special characters in the name, just to be safe.
4/ Test with this line $file = curl_file_create($file_path, $file_type, $file_name ); instead of your version, and note that this one includes the file type which in your case should be image/png if I am not mistaken
5/ Remove the boundary=12121 from the header in case it is causing issues.

thank you
at least I have it working with curl right now

but maybe someone made it working with GuzzleHttp?
I am using:

        $data['multipart'] = [
            [
                'name'     => 'attachment',
                'contents' => Utils::tryFopen(storage_path('app/public/image.png'), 'r'),
            ]
        ];

and i tried fopen() and file_get_content() for 'contents'

but it always:
'{"err":"No attachment supplied","ECODE":"ATTCH_039"}'

I am using Guzzle for all other requests
so, please, let me know with an example
