Is there any statndard pattern for returning the JSON response

Question

I am using the following design for JSON response

{
    "metadata": [
        "count": <count of entities>
    ],
    "debug": [
        <debug messages>
    ],
    "results": [
        <List of results>
    ],
    "errors": [
        <List of errors>
    ]
}

Is there any better design or blueprint for returning the response JSON
