validation errors

The following query

query MyQuery {
  aircraftFromAircraftId(aircraftId: "12345") {
    history {
      registration
    }
  }
}

returns this:

{
  "data": null,
  "errors": [
    {
      "message": "3 validation errors for AircraftHistories\n0._id\n  Input should be a valid string [type=string_type, input_value=-824849624, input_type=int]\n    For further information visit https://errors.pydantic.dev/2.5/v/string_type\n0._created\n  Field required [type=missing, input_value={'_id': -824849624, 'natu...llectday': '2025-09-18'}, input_type=dict]\n    For further information visit https://errors.pydantic.dev/2.5/v/missing\n0._updated\n  Field required [type=missing, input_value={'_id': -824849624, 'natu...llectday': '2025-09-18'}, input_type=dict]\n    For further information visit https://errors.pydantic.dev/2.5/v/missing",

        }
      ],
      "path": [
        "aircraftFromAircraftId"
      ]
    }
  ]
}

There seems to be a change with id in DHA
