Description

Observed behavior

When requesting a file upload URL from Studio, Ricecooker does utilize the original file name, but that is eventually discarded, meaning the filename for cheffed files will default to file

the issue is that ricecooker's implementation of the file upload URL stuff [...] creates the file object to get the upload URL, but then an entirely new file object gets created during the channel upload, so that data gets discarded.

Expected behavior

Ricecooker should use preserve the filename

User-facing consequences

These files end up showing Unknown filename to the end user.

Context

https://github.com/learningequality/studio/issues/4814

Looking at the following bit of code it does appear Ricecooker passes the filename along in its initial request for an upload URL, but according to the above quote, that gets discarded
