So I'm using the Http client and attaching a file to the request.
Using a stream works fine as per the docs
Http::attach('file', fopen('path-to-file', 'r'))->post('...')
However using a string (again as per the docs) does not seem to work
The file attachment is not sent in this case - server returns error that no file was sent.
Anyone else had this issue. Is it just me or...?
