setting task location through task API silently fails

Posting the JSON below to /api/v2/tasks silently fails with

WARN - Invalid json for type: {"obj.location":[{"msg":["error.expected.jsstring"],"args":[]}]}

on the console.

[
    {
        "name": "ExampleTask",
        "identifier": "Custom_Identifier",
        "parent": 2,
        "instruction": "Task instruction",
        "geometries": {
            "type": "FeatureCollection",
            "features":
                [{
                    "type": "Feature",
                    "geometry": {
                        "type": "Point",
                        "coordinates": [77.6255107,40.5872232]
                    },
                    "properties": {}
                }]
        },
        "location": {"type":"Point","coordinates":[77.6255107,40.5872232]},
        "status": 0
    }
]

Start by reproducing the POST to /api/v2/tasks with the JSON shown, then trace the task API's validation of the location field. Done means the request accepts the provided point location without silently failing or logging the error.expected.jsstring warning.
