@v-kellyluo, is the uploaded file the correct file?

[v-kellyluo]

@MRayermannMSFT , yes, the uploaded file is a correct file under the default location (/home//Downloads).

@richardMSFT , please research if this is expected on this version of ubuntu. Perhaps the file path the app sees is odd because of some sort of containerization the app is placed in by the snap runtime?

From what I've researched, this seems to be the expected behavior for a confined application in snap using xdg desktop portals (https://forum.snapcraft.io/t/home-path-is-translated-into-run-user-1000/15415/6).

From the snapcraft documentation on portals: "Files are fuse-mounted to /run/user//doc// in order to give your application access to it. So the path your application sees is different from the path a user chose, even though both are the same file." (https://snapcraft.io/docs/xdg-desktop-portals). This seems to be inline with what we're seeing for the upload location.

I don't see anywhere we're explicitly enabling portal support in our snap, but electron supports native file chooser dialogs using XDG Desktop Portal (electron/electron#19159). Since we use electron's dialog module (which displays native system dialogs) and showOpenDialog function for our file picker during uploads, this could be why we are getting these paths.

As for why this is reproducing for ubuntu 20.04 and not 22.04, I'm not sure. That requires further research.
