I am trying to delete many records for a data source. Why do I get the following error? I am the only one performing the query.

Query:

```auto
mutation {
  deleteqAanswer(filter: {idDitio: {eq: null}}) {
    deletedCount
  }
}

```

Error:

```auto
{
  "errors": [
    {
      "message": "WriteConflict error: this operation conflicted with another operation. Please retry your operation or multi-document transaction.",
      "locations": [
        {
          "line": 2,
          "column": 3
        }
      ],
      "path": [
        "deleteqAanswer"
      ]
    }
  ],
  "data": {
    "deleteqAanswer": null
  }
}

```

Hi,

Are there any elements in the ObjectClass that are being accessed frequently?  
This might occur if someone is writing to the same document at the same time as the deletion.

You can read more about WriteConflicts [here](https://docs.appfarm.io/reference/appfarm-client/warnings-and-errors#action-node-failed-persist-objects-greater-than-mongoservererror-writeconflict-error) 🙂
