Template variables not detected in API /api/v1/graph/embed

[ricardojlrufino]

Describe the bug Template variables not detected in API /api/v1/graph/embed Using a more complete "graph_json", not detect: template_variables

Working code:

graph_json = {
    "requests": [{
        "q": "avg:jvm.non_heap_memory{env:$env,service:$service}"
    },
    {
        "q": "max:jvm.non_heap_memory{env:$env,service:$service}"
    }],
    "viz": "timeseries",
    "events": []
}

graph_json = json.dumps(graph_json)

response = api.Embed.create(
    graph_json=graph_json,
    timeframe="1_hour",
    size="medium",
    legend="no"
)

But if a use JSON exported form, Dashboard -> Edit Widget -> JSON

like>

graph_json = {
    "viz": "timeseries",
    "requests": [
        {
            "style": {
                "palette": "grey",
                "type": "dashed",
                "width": "normal"
            },
            "type": "line",
            "response_format": "timeseries",
            "queries": [
                {
                    "data_source": "metrics",
                    "name": "query1",
                    "q": "max:jvm.heap_memory{env:$env,service:$service}"
                },
                {
                    "data_source": "metrics",
                    "name": "query2",
                    "q": "min:jvm.heap_memory{env:$env,service:$service}"
                }
            ]
        },
        {
            "style": {
                "palette": "warm",
                "type": "solid",
                "width": "thin"
            },
            "type": "line",
            "response_format": "timeseries",
            "queries": [
                {
                    "data_source": "metrics",
                    "name": "query1",
                    "q": "max:jvm.heap_memory_max{env:$env,service:$service}"
                }
            ]
        },
        {
            "style": {
                "palette": "grey",
                "type": "solid",
                "width": "normal"
            },
            "type": "line",
            "response_format": "timeseries",
            "queries": [
                {
                    "data_source": "metrics",
                    "name": "query1",
                    "q": "avg:jvm.heap_memory{env:$env,service:$service}"
                }
            ]
        }
    ]
}

Not detect template variables ! Returns: {'embed_id': 'XX', 'template_variables': [ ], 'html': ".........."}

Expected behavior API must need 'template_variables'
