    //Convert a Json to Query
    let query = ngsi.createQuery({
    "id":"Device.*",
    "type":"Device",
    "options":"keyValues",
    "dateObserved" : ">=2018-02-20T16:54:03.931-06:00"
    })
    console.log(query)

Output

    ?id=Device.*&Device&type=Device&options=keyValues&q=dateObserved>=2018-02-20T16:54:03.931-06:00

    cb.getWithQuery(query)
    .then((result) => console.log(result))
    .catch((err) => console.log(err))
