Creating an entry with a matrix field using GraphQL

Question

I am trying to create a new entry in Craft CMS using GraphQL. The entry has a matrix field called "vehicles" that has a single block called "vehicle". This block has a single field called "vehicleValue".

In GraphiQL I am using the following query to save a new entry:

mutation SaveVehicle($vehicles: vehicles_MatrixInput) {
  save_applications_application_Entry(vehicles: $vehicles) {
    uid
    vehicles {
      ... on vehicles_vehicle_BlockType {
        vehicleValue
      }
    }
  }
}

Then I pass the following variables:

{
  "vehicles": {
    "blocks": [
      {
        "vehicle": {
          "vehicleValue": 111
        }
      }
    ]
  }
}

The query runs and a new entry is created but the matrix field is empty.

The schema is public so no auth is required.

I am new to using Craft and GraphQL so it is probably something simple. Any help would be greatly appreciated.

Try this:

mutation SaveVehicle($vehicles: [vehicles_MatrixBlockContainerInput], $sortOrder: [QueryArgument]) {
  save_applications_application_Entry(vehicles: {blocks: $vehicles, sortOrder: $sortOrder}) {
        uid
        vehicles {
            ...on vehicles_vehicle_BlockType {
                vehicleValue
            }
        }
    }
}

And your variables:

{
    "sortOrder":"new1",
    "vehicles": [
        {
            "vehicle": {
                "id": "new1", 
                "vehicleValue": "111"
            }
        }
    ]
}
