Частное репозиторий github в package.json, нарушающий развертывание веб-сайта Azure

Попытка развернуть приложение Express на "веб-сайте" Azure через Github. У меня есть частный репозиторий в package.json зависимости:

"dependencies": {
  "express: "~3.4.0",
   ...
  "private-repo": "git+ssh://[email protected]:private/repo.git"
}

К сожалению, вот трассировка стека:

Command: C:\DWASFiles\Sites\website002\VirtualDirectory0\site\deployments\tools\deploy.cmd
