Cannot access PUT files outside of formdata.

[kattschan]

Describe the bug

I have a PUT function inside of a +server.js file. If a file is uploaded to the server and it is not in a multipart form, there is no way to access the file.

Reproduction

Reproduction can be found here: https://github.com/kattschan/sveltekit-bugreport-repro. Run it on your machine (StackBlitz wouldn't play nice with curl), and try, for instance curl --upload-file package.json http://localhost:5173/package.json and see what gets outputted to console. Using all of the ways to extract data from the response, there is no way to get the file attached in this manner.

Logs

TypeError: Content-Type was not one of "multipart/form-data" or "application/x-www-form-urlencoded".

Severity

serious, but I can work around it

Additional Information

my current workaround is to use an express server with middleware, but this introduces added complexity.
