**What command line arguments are you passing?**

**What does your `config.forge` data in `package.json` look like?**

“forge”: { “make_targets”: { “win32”: [ “squirrel” ], “darwin”: [ “zip” ], “linux”: [ “deb”, “rpm” ] }, “electronPackagerConfig”: { “packageManager”: “npm” }, “electronWinstallerConfig”: { “name”: “Paradise” }, “electronInstallerDebian”: {}, “electronInstallerRedhat”: {}, “github_repository”: { “owner”: “”, “name”: “” }, “windowsStoreConfig”: { “packageName”: “Paradise”, “name”: “paradise-client” } }

**Please provide either a failing minimal testcase (with a link to the code) or detailed steps to
reproduce your problem. Using `electron-forge init` is a good starting point, if that is not the
source of your problem.**

Run `electron-forge start`
