Query does not return results if filter contains numeric value

[andreachild]

If the graphQL query contains a filter with a numeric value, the query will not return any results because the converted open cypher query parameter value will be a string, not a numeric value.

Example (note that runways value is numeric 2):

query MyQuery {
  getNodeAirports(filter: {runways: 2}) {
    type
    city
    icao
    code
    country
    lat
    longest
    runways
    desc
    lon
    region
    elev
  }
}

Resolver outputs this open cypher query (note the quotes around the runways value 2) :

Resolver:  {
  query: 'MATCH (getNodeAirports_Airport:`airport`{runways: $getNodeAirports_Airport_runways})\n' +
    'RETURN collect({type: getNodeAirports_Airport.`type`, city: getNodeAirports_Airport.`city`, icao: getNodeAirports_Airport.`icao`, code: getNodeAirports_Airport.`code`, country: getNodeAirports_Airport.`country`, lat: getNodeAirports_Airport.`lat`, longest: getNodeAirports_Airport.`longest`, runways: getNodeAirports_Airport.`runways`, desc: getNodeAirports_Airport.`desc`, lon: getNodeAirports_Airport.`lon`, region: getNodeAirports_Airport.`region`, elev: getNodeAirports_Airport.`elev`})',
  parameters: { getNodeAirports_Airport_runways: '2' },
  language: 'opencypher',
  refactorOutput: null
}
