ValidationError：validation失败mongoose
你好，我正在尝试连接Node.js与Facebook。 我正在关注这个博客条目。 有人能帮我吗？
我得到这个错误：

{ "name": "testapp", "version": "0.0.0", "description" : "Something" "engines": { "node": "4.2.x", "npm": "3.3.x", }, "dependencies": { "body-parser": "~1.12.0", "cookie-parser": "~1.3.4", "debug": "~2.1.1", "express": "~4.12.2", "fs-extra": "^0.18.4", "jade": "~1.9.2", "jsonwebtoken": "5.0.4", "morgan": "~1.5.1", "multer": "^1.0.3", "serve-favicon": "~2.2.0" } }
现在我改变了必填字段，我没有得到错误。
password : { type : String, // <-- no }
这可能是一个原因
