Problem using forecastService

[joanbga]

Hi, I've problems using node-google-dfp. When I use service like InventoryService, all works well. But, I'm trying to use ForecastService (getAvailabilityForecast) that needs 2 params btw and doesn't work.
Here is some code:

const Dfp = require('node-google-dfp');
const dfpUser = new Dfp.User(MY_NETWORK_CODE, 'test pub', 'v201708');
const google = require('googleapis')
const ADVERTISER_ID = 'MY_ADVERTISER_ID'

const jwtClient = new google.auth.JWT(
    'MY_EMAIL',
    './cred.pem',
    null,
    ['https://www.googleapis.com/auth/dfp']);
dfpUser.setClient(jwtClient)

const endDatetime = moment().add(30, 'days').toISOString()

console.log('end_datetime ->', endDatetime)

const    lineItem = {
  targeting: {
    inventoryTargeting: {
      targetedAdUnits: [
        {
          adUnitId: 'MY_ADD_UNIT_ID',
          includeDescendants: true,
        }
      ]
    },
    geoTargeting: {
      targetedLocations: [
        {
          id: '9068897'
        }
      ]
    },
  },
  lineItemType: 'SPONSORSHIP',
  startDateTimeType: 'IMMEDIATELY',
  endDateTime: endDatetime,
  costType: 'CPM',
  primaryGoal: {
    units: '50',
    unitType: 'IMPRESSIONS',
    goalType: 'DAILY'
  },
  contractedUnitsBought: '100',
  creativeRotationType: 'EVEN'
}

const prospectiveLineItem = {
  'lineItem': lineItem,
  'advertiserId': ADVERTISER_ID
}

const    forecastOptions = {
  includeContendingLineItems: true,
  includeTargetingCriteriaBreakdown: true
}

dfpUser.getService('ForecastService', (err, service) => {
  console.log('service ->', service)
  /* LOG:
    service -> { getAvailabilityForecast: [Function],
    getAvailabilityForecastById: [Function],
    getDeliveryForecast: [Function],
    getDeliveryForecastByIds: [Function] }
  */
  service.getAvailabilityForecast({lineItem: prospectiveLineItem, forecastOptions: forecastOptions}, (err, result) => {
    console.log('err ->', err)
    // console.log('result ->', result)
  })
})

Here is my err output:

body: '<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">soap:Bodysoap:Faultsoap:ClientUnmarshalling Error: cvc-complex-type.2.4.d: Invalid content was found starting with element 'geoTargeting'. No child element is expected at this point. </soap:Fault></soap:Body></soap:Envelope>' }

I don't understand this error since inventoryTargeting can have geoTargeting parameter. Do you have any idea why this call return this error ?
Thanks !! :)

Found the solution:
Object given to the soap api has to be in the order defined in the dfp api documentation.

Exemple:
Good

{
   startDateTime: {...},
   endDateTime: {...}
}

Bad

{
   endDateTime: {...},
   startDateTime: {...}
}
