[RedDevilHat]

Hello, i try test API and have strange error

my json output

{"id":29,"first_name":"Test","last_name":"Testov","avatar":"","language":{"id":1,"code":"ru","name":"\u0420\u0443\u0441\u0441\u043a\u0438\u0439"},"country":{"id":1,"name":"\u0420\u043e\u0441\u0441\u0438\u044f"},"timezone":{"id":383,"title":"Europe\/Moscow","abbreviation":"MSK","utc_offset":"03:00:00","if_dst":false},"roles":["ROLE_USER"]}

and in formated

{
	"id": 29,
	"first_name": "Test",
	"last_name": "Testov",
	"avatar": "",
	"language": {
		"id": 1,
		"code": "ru",
		"name": "Русский"
	},
	"country": {
		"id": 1,
		"name": "Россия"
	},
	"timezone": {
		"id": 383,
		"title": "Europe/Moscow",
		"abbreviation": "MSK",
		"utc_offset": "03:00:00",
		"if_dst": false
	},
	"roles": [
		"ROLE_USER"
	]
}

My apiary json

{
    "id": 1,
    "first_name": "Иван",
    "last_name": "Иванов",
    "avatar": "http://test.com/bundles/app/static/images/default_users_images/undefined_user4.jpg",
    "language": {
        "code": "ru",
        "name": "Русский"
    },
    "country": {
        "id": 1,
        "name": "Россия",
    },
    "timezone": {
        "title": "US/Samoa",
        "abbreviation": "SST",
        "utc_offset": "-11:00:00",
        "if_dst": false
    },
    "roles": [
        "ROLE_USER",
        "ROLE_ADMIN"
    ]
}

and apiary say me after test

Can't validate. Expected body Content-Type is application/json but body is not a parseable JSON: Parse error on line 12: ...ame": "Россия", }, "timezone": { ----------------------^ Expecting 'STRING', got '}'

what's wrongs?

It is a strange sounding error, but actually it is caused by the trailing , at the end of "name": "Россия",in the apiary json. If you try to validate the apiary json in http://jsonlint.com/ you'll get the same error.

Deleting that , solves the problem.

I think about this error it is necessary to disclose at the time of validation to the blueprint editor, but thank you

This is basic Dredd functionality - to show differences and issues with JSON. The error does need to be more clear. I hope we can address this somehow once we're improving the CLI output.
