I tried sending a request to this endpoint using Postman, but the response body I got seems to be different from what is stated on the Swagger doc. The doc seems to be confusing, this is what I got on Postman:

{
    "data": [
        {
            "_id": String,
            "name": String,
            "createdAt": "2023-06-22T21:01:05.684Z",
            "updatedAt": "2023-06-22T21:01:05.684Z",
            "__v": 0
        }
    ]
}
