Validating and baking open badges

Question

I've been trying to generate open badges for a while, but so far none of them will validate or bake using the online tools.

I've tried a variety of different combinations. Here's the one I'm using currently (sites removed due to being preproduction sites) :

On the site at http://example.org/badge/5ab0d10a6a02f :

{
    "@context":"https://w3id.org/openbadges/v1",
    "type":"Assertion",
    "id":"http://example.org/badge/5ab0d10a6a02f",
    "uid":"5ab0d10a6a02f",
    "recipient":
    {
        "type":"email",
        "identity":"email@example.org",
        "hashed":false
    },
    "issuedOn":1521564293,
    "badge":"http://example.org/badge-class.json",
    "verify":
    {
        "type":"hosted",
        "url":"http://example.org/badge-issuer.json"
    }
}

On the site at http://example.org/badge-class.json :

{
    "@context": "https://w3id.org/openbadges/v1",
    "id": "http://example.org/badge-class.json",
    "type": "BadgeClass",
    "name": "Badge",
    "description": "Description",
    "image": "http://example.org/badge.png",
    "criteria": "http://example.org/criteria",
    "issuer": "http://example.org/badge-issuer.json"
}

and at http://example.org/badge-issuer.json :

{
    "@context": "https://w3id.org/openbadges/v1",
    "id": "http://example.org/badge-issuer.json",
    "type": "Issuer",
    "name": "Name",
    "url": "http://www.example.org/",
    "telephone" : "xxxxxxxxx",
    "description" : "description",
    "image" : "http://www.example.org/logo.png",
    "email" : "email@example.org"
}

Once properly hosted on a real site, I tried to validate and bake it, but I get the following errors :

For the validators :

Using the baker :

Could not parse json: Unexpected token <

Using the baker API :

{
    "message":"could not get assertion: invalid JSON",
    "stack":"Error: could not get assertion: invalid JSON
        at makeError (/app/lib/analyze-assertion.js:6:26)
        at Request._callback (/app/lib/analyze-assertion.js:31:23)
        at Request.self.callback (/app/node_modules/request/request.js:187:22)
        at Request.emit (events.js:98:17)
        at Request.<anonymous> (/app/node_modules/request/request.js:1126:10)
        at Request.emit (events.js:95:17)
        at IncomingMessage.<anonymous> (/app/node_modules/request/request.js:1046:12)

        at IncomingMessage.emit (events.js:117:20)
        at _stream_readable.js:944:16",
    "code":"parse"
}

What part of this badge is causing the issues?

Maybe the last eight (8) lines of the badge assertion file at http://example.org/badge/5ab0d10a6a02f should be:

{

    ...
    ... 
    "badge":"http://example.org/badge-class.json",
    "issuer":"http://example.org/badge-issuer.json",
    "verify":
    {
        "type":"hosted",
        "url":"http://example.org/badge/5ab0d10a6a02f/THIS-BADGE-ASSERTION-FILE.json"
    }
}

where THIS-BADGE-ASSERTION-FILE.json is the badge assertion JSON file and is precisely the file whose contents we are modifying. That is to say, the "verify" URL should point to the badge assertion JSON file (that resides within the folder http://example.org/badge/5ab0d10a6a02f/) and not to the badge-issuer.json file which is the badge issuer JSON file.

You may want to have a look at [Step 2: Award the Badge](https://github.com/mozilla/openbadges-backpack/wiki/New-Issuers:-Give-Yourself-a-Badge#step-2-award-the-badge) from the [Wiki pages of Mozilla Open Badges Backpack on GitHub](https://github.com/mozilla/openbadges-backpack/wiki)). — user49177, Jan 31 '19 at 05:18
