teams-for-linux: Appears as electron after launch

[emilioziniades]

Nixpkgs version

• Unstable (26.05)

Describe the bug

I am using Gnome with wayland on NixOS. After launching teams-for-linux, the incorrect icon is used for Teams in the system tray, and the application is named 'electron'.

This is sort of related to #505078, but it's slightly different because it's not a version mismatch. Both nixpkgs and upstream use electron v41. Rather, I believe it is because upstream is missing desktopName in its package.json.

Unlike the obsidian case, where upstream refused to fix (and rightly so because it was a packaging issue), here the solution might be to fix it upstream.

Alternatively we could go the route of #505535 and patch the package.json when we package the application.

Steps to reproduce

nix run nixpkgs#teams-for-linux. Observe the icon and app name in the system tray.

Expected behaviour

there should be the teams logo and the application should be named 'Teams for Linux'.

Yeah, I forgot to try and upstream the change... i have a local patch i use

      home.packages = [
        (pkgsMaster.teams-for-linux.overrideAttrs (old: {
          # NOTE: Fix electron app_id
          postPatch = (old.postPatch or "") + ''
                    substituteInPlace package.json \
                      --replace-fail '"name": "teams-for-linux",' '"desktopName": "teams-for-linux.desktop",
            "name": "teams-for-linux",'
          '';
        }))
      ];

Thanks, I ended up doing something similar with a local patch:

(pkgs.teams-for-linux.overrideAttrs (old: {
  nativeBuildInputs = old.nativeBuildInputs ++ [ pkgs.yq-go ];
  postPatch = (old.postPatch or "") + ''
    yq -iP '.desktopName = "teams-for-linux.desktop"' package.json
  '';
}))

In terms of a more permanent fix, I opened (and then closed lol) an upstream PR into teams-for-linux. I closed it because I came across this PR electron/electron#51424 which seems to revert to the old behaviour of deriving desktopName from name in package.json.

Confirmed that on latest unstable nixpkgs, Teams For Linux, which has electron 41.7.1, appears correctly:
