Hi there,

I have a collection with following schema:

QuoteInformationSchema = {
  name: 'QuoteInformation',
  properties: {
    _id: 'objectId',
    _partition: 'string',
    quoteTitle: 'string?',
    quoteNumber: 'string?',
    quoteSections: 'QuoteInformation_quoteSections[]'
 },
  primaryKey: '_id',
};

QuoteInformation_quoteSectionsSchema = {
  name: 'QuoteInformation_quoteSections',
  embedded: true,
  properties: {
    sectionNumber: 'string?',
    sectionTitle: 'string?',
      travelExpenses: 'QuoteInformation_quoteSections_travelExpenses[]'
  },
};

QuoteInformation_quoteSections_travelExpensesSchema = {
  name: 'QuoteInformation_quoteSections_travelExpenses',
  embedded: true,
  properties: {
    travelExpenseId: 'string?',
    travelExpensePartition: 'string?',
    travelExpenseName: 'string?',
    travelExpensePrice: 'string?'
  },
};

When I try to get a QuoteInformation object with the following query:

quoteInformation(query: { quoteNumber: "ABC-123" }) {
    quoteTitle
    quoteSections {
      sectionNumber
      sectionTitle
      travelExpenses {
          travelExpenseId
  	      travelExpensePartition
          travelExpenseName
          travelExpensePrice
      }
    }
  }

I have the following response:

{
  "data": {
    "quoteInformation": {
      "quoteTitle": "Remplacement bloc WC",
      "quoteSections": [
        {
          "sectionNumber": "1",
          "sectionTitle": "Mise en oeuvre",
          "travelExpenses": [
            {
              "travelExpenseId": null,
              "travelExpenseName": null,
              "travelExpensePartition": null,
              "travelExpensePrice": null
            }
          ]
        }
      ]
    }
  }
}

I tried with GraphiQL and with a Flutter app and I have the same answer.

I’m sure that travelExpenseId, travelExpensePartition, travelExpenseName and travelExpensePrice are not null, so why do I have this response?

Thanks for your help!
