I’m trying to make a POST request to a newly deployed vercel server. I am having trouble with the request in POSTMan and am getting error 500 when I try to request it from postman. My swift code only returns error 405. Here is my code:

    func callRequest() {
        let full_path: String = "https://suno-api-six-henna.vercel.app/api/generate"
        let json: [String: Any] = ["prompt": "A popular heavy metal song about war, sung by a deep-voiced male singer, slowly and melodiously.",
                                   "make_instrumental": "false", "wait_audio": "true"]
        
        let jsonData = try? JSONSerialization.data(withJSONObject: json)

        if let url = URL(string: full_path) {
            var request = URLRequest(url: url)
            request.httpMethod = "POST"
            request.setValue("application/json; charset=utf-8", forHTTPHeaderField: "Content-Type")
            request.setValue("application/json; charset=utf-8", forHTTPHeaderField: "Accept")
            request.httpBody = jsonData

            do {
                let task = URLSession.shared.dataTask(with: url) { data, response, error in
                    //This converts the optionals in to non optionals that could be used further on
                    //Be aware this will just return when something goes wrong
                    guard let data = data, let response = response, error == nil else{
                        print("Something went wrong: error: (error?.localizedDescription ?? "unkown error")")
                        return
                    }
                    print(response)
                    let test = String(decoding: data, as: UTF8.self)
                    print(test)
                }
                
                task.resume()
            }
        }
    }

Feel free to use POSTMan or make a request to the link in the full_path variable. Please help me debug! Could it be the headers?
