GraphQL query in Neo4j DataBase missing data

Question

I try use GraphQL for query on Neo4j DataBase but I don't receive all informations

here is the Graph

I have 2 documents for the DueDiligence I query. but I have only 1 document on the query return

query DueDiligences {
  dueDiligences (where: { ddId: "2"}){
    ddId
    provideDocument {
      docName
      docId
    }
  }
}

// return

{
  "data": {
    "dueDiligences": [
      {
        "ddId": "2",
        "provideDocument": {
          "docName": "KBIS",
          "docId": "2"
        }
      }
    ]
  }
}

How could I do to have all documents on the return??

The index

type Document {
  docId: ID!
  docDate: LocalDateTime
  docName: String!
  docStatus: String!
  docType: String
  docEncoding: String
  duediligencesProvide: DueDiligences @relationship(type: "PROVIDE", direction: IN)
}

type DueDiligences {
  ddId: ID!
  counterPartyRisk: String
  countryRisk: String
  ddClose: String
  ddOpen: String!
  ddStatus: String!
  ddType: String
  operationalRisk: String
  sumRisk: String
  investmentvehiculesOdited: InvestmentVehicules @relationship(type: "ODITED", direction: IN)
  provideDocument: Document @relationship(type: "PROVIDE", direction: OUT)
  investFunds: Funds @relationship(type: "INVEST", direction: OUT, properties: "Invest1")
  eurazeoManage: Eurazeo @relationship(type: "MANAGE", direction: IN)
}
