When you pass on a file (URL) using form-data it doesn't use the Content-Disposition filename

[mkasson]

This issue submission follows a conversation with Fokke.

Your "creates/upload.js" shows use of Form-Data and request to upload a file presented to a create by a trigger. However, I have seen Form-Data is not receiving the filename from the Content-Disposition line. I have had to set filename manually (providing a placeholder) using the Alternate Submission Methods and submitted PR #7 relating to this.

Form-Data says that it "can recognize and fetch all the required information from common types of streams (fs.readStream, http.response and mikeal's request)". This suggests that the filename is not getting to request and/or Form-Data correctly. (Perhaps the issue is in stashing and/or dehydration - though I admit I am not super familiar with the impact of those.) Fokke and I have both observed Form-Data using the value from path in this method

Thank you for your attention to this.

This may be a bug in form-data which as https://www.npmjs.com/package/form-data#alternative-submission-methods says:

Form-Data can recognize and fetch all the required information from common types of streams (fs.readStream, http.response and mikeal's request), for some other types of streams you'd need to provide "file"-related information manually:

This example uses request but @mkasson found that when you follow the example the multipart body generated by form-data does not use the filename from the file URL, while we do send the filename as part of the Content-Disposition.
