elm-package.json无法加载

Question

我正在尝试在Intellij中创建Elm项目。为此，我使用了相当标准的elm-package.json文件：

{
   "version": "1.0.0",
   "summary": "helpful summary of your project, less than 80 characters",
   "repository": "https://github.com/user/project.git",
   "license": "BSD3",
   "source-directories": [
       "."
   ],
   "exposed-modules": [],
   "dependencies": {
       "elm-lang/core": "5.1.1 <= v < 6.0.0",
       "elm-lang/html": "2.0.0 <= v < 3.0.0"
    },
    "elm-version": "0.18.0 <= v < 0.19.0"
}

我正在尝试加载该项目，并遇到以下故障：

org.elm.workspace.ProjectLoadException: The 'type' field is 'null', but expected either 'application' or 'package'

该“类型”字段似乎没有任何文档！它是什么？我在哪里放置？更重要的是，当我使用elm-package install创建json文件时，为什么不与其余json文件一起生成？？
