When testing the following two endpoints, I get different results for the array of owners and tags. The former should be identical to the response of the latter endpoint.

`/api/v1/dags/{dag_id}/details`:

```json
{

  "owners": [],
  "tags": [
    {},
    {}
  ],
}
```

`/api/v1/dags/{dag_id}`:

```json
{

  "owners": [
    "airflow"
  ],
  "tags": [
    {
      "name": "example"
    },
    {
      "name": "example2"
    }
  ]
}
```

        assert response.status_code == 200
