Need $ref as a variable in open-api-spec.yml file

Hi Prasanna_Ailuri 

Are you using Swagger-Codegen to generate your server implementation?

I've just generated a Java SpringBoot server stub from the OpenAPI definition shared above and the response from the GET '/users' is as follows (which looks correct):

[
    {
        "meta": [
            {
                "display": "display",
                "value": "value",
                "$ref": "$ref"
            },
            {
                "display": "display",
                "value": "value",
                "$ref": "$ref"
            }
        ],
        "id": "id"
    },
    {
        "meta": [
            {
                "display": "display",
                "value": "value",
                "$ref": "$ref"
            },
            {
                "display": "display",
                "value": "value",
                "$ref": "$ref"
            }
        ],
        "id": "id"
    }
]

I suspect your issue is related to the usage of the keyword $ref. I would recommend that you change the name of that property so that it does not clash with a JSON Schema keyword.

Thanks,
