Unable to parse JSON using decode function

Hi, I have a problem when trying to parse the JSON which used to work before but it is broken now and I have no idea why it is.

JSON data:

{
  "success": true,
  "data": {
    "email": "example@gmail.com",
    "password": "$2b$10$flI1flm1Ptas33z3uBct6.UkhgiRmv/qIzJCVe2PIUycUFIh0BZfW",
    "favouriteRestaurants": [],
    "favouriteDishes": [],
    "_id": "655adf2386348c2be2360852",
    "reservations": [],
    "createdAt": "2023-11-20T04:22:59.831Z",
    "updatedAt": "2023-11-20T04:22:59.831Z",
    "__v": 0
  }
}

And my model is

struct SignupResponse: Decodable {
let email: String?
    let password: String?
    let id: String?

    private enum CodingKeys: String, CodingKey {
        case data
        case email
        case password
        case id = "_id"
    }

    init(from decoder: Decoder) throws {
        let container = try decoder.container(keyedBy: CodingKeys.self)
        let dataContainer = try container.nestedContainer(keyedBy: CodingKeys.self, forKey: .data)

        email = try dataContainer.decodeIfPresent(String.self, forKey: .email)
        password = try dataContainer.decodeIfPresent(String.self, forKey: .password)
        id = try dataContainer.decodeIfPresent(String.self, forKey: .id)
}

I couldn't figure out the reason. Thank you for your help!
