File upload example from shiny gallery is currently not working in RCloud #2

Whenever user loads a file using shiny API a POST request is made to the session which looks something like below, which tries to write the file to tempdir()

Remote Address:127.0.0.1:8080 Request URL:http://127.0.0.1:8080/session/b248c49e4d4632e19db135cc58af6d8c/upload/1100eae0eefe31cb46d74cdc?w= Request Method:POST Status Code:404 Code 404

Shiny handleRequest function is not able to handle the above request in RCloud.

We can use RCloud file upload as an alternative but we cannot connect them back to shiny callback/render functions

I see. Thanks for tracking this down. Do you see if it's possible to replace the function on the JavaScript side that is making the request? I assume they are using jquery ajax but perhaps they have a wrapper function?

This is what we did for the websocket itself, and I'd prefer this to adding a server (although we could presumably handle http://.../session/ as well).

Fixed in rcloud.shiny 0.4 (RCloud 1.7)
