Swift - Codable "Number 2.87 is not representable in Swift"

I have the following struct:

struct CustomerEntries: Codable {
    var date: String
    var customer_rate: Double
    var percentage: Double
    
    enum CodingKeys: String, CodingKey {
        case date
        case customer_rate = "customer-rate"
        case percentage = "percentage-change"
    }
}

I decode JSON using Alamofire's serializingDecodable() such as this:

let response = await AF.request("https://api.xx.com/endpoint", parameters: params, headers: headers)
                .validate()
                .serializingDecodable(CustomerEntries.self)
                .response

It works fine for the first few results (I traced it), and eventually the response fails for a specific return value of 2.87 for customer_rate with the error "Number 2.87 is not representable in Swift".

The JSON returned value is:

"customer-rate": 2.87

I tried decoding to String instead but since the JSON returned value is not enclosed in double quotes, this time the response fails with the error "Expected to decode String but found number instead".

Any ideas on how to resolve this?
