Managing Packages with Npm - package.json should have a valid "author" key

My test result still say “package.json should have a valid “author” key” but I do have author key in my file.
What is wrong with it?

code:

{
	"author": "Eriko Dott",
	"name": "fcc-learn-npm-package-json",
	"dependencies": {
		"express": "^4.14.0"
	},
	"main": "server.js",
	"scripts": {
		"start": "node server.js"
	},
	"engines": {
		"node": "8.11.2"
	},
	"repository": {
		"type": "git",
		"url": "https://idontknow/todo.git"
	}
}

never mind, I figure out by using the link from this: How-to-use-package-json-the-core-of-any... first api challenge not passing
