Support easy debugging of json responses too like this:

                do {
                    // Attempt to deserialize the Data object to a JSON object
                    let jsonObject = try JSONSerialization.jsonObject(with: data, options: [])

                    // Convert the JSON object to a pretty-printed string
                    let decodedJsonData = try JSONSerialization.data(withJSONObject: jsonObject, options: [.prettyPrinted])
                    DebugLog.shared.log(String(data: decodedJsonData, encoding: .utf8) ?? "")
                } catch {
                    print("Error converting Data to JSON decoded string: \(error)")
                }
