BasicNetwork.performRequest: Unexpected response code 500 for


Maybe this problem has been posted before but it does not solve my case. I am trying to send data from android to mysql database using laravel as the backend. I have developed the restful Api. This is my code.

         try {
                RequestQueue requestQueue = Volley.newRequestQueue(SignUpActivity.this);

                JSONObject jsonBody = new JSONObject();
                jsonBody.put("email","[email protected]");
                final String requestBody = jsonBody.toString();

                StringRequest stringRequest = new StringRequest(Request.Method.POST, url, new Response.Listener<String>() {
                    public void onResponse(String response) {
                        Log.i("VOLLEY", response);
                }, new Response.ErrorListener() {
                    public void onErrorResponse(VolleyError error) {
                        Log.e("VOLLEY", error.toString());
                }) {
                    public String getBodyContentType() {
                        return "application/json; charset=utf-8";

                    public byte[] getBody() throws AuthFailureError {
                        try {
                            return requestBody == null ? null : requestBody.getBytes("utf-8");
                        } catch (UnsupportedEncodingException uee) {
                  "Unsupported Encoding while trying to get the bytes of %s using %s", requestBody, "utf-8");
                            return null;
                        } catch (Exception e) {
                            return null;
                    protected Response<String> parseNetworkResponse(NetworkResponse response) {
                        String responseString = "";
                        if (response != null) {
                            responseString = String.valueOf(response.statusCode);
                            // can get more details such as response.headers
                        return Response.success(responseString, HttpHeaderParser.parseCacheHeaders(response));
            } catch (JSONException e) {



Laravel Code

 public function signUp(Request $request){
    $success = "Successful";
    $validator = Validator::make($request->all(), [
        'email' => 'required|email|max:255|unique:users',
        'password' => 'required|min:5'

    if ($validator->fails()){
        return response()->json(['error'=>$validator->errors()], 401);
        'email' => $request->get('email'),
        'username' => $request->get('username'),
        'password' => Hash::make($request->get('password')),
        'vCode' => $request->get('vCode')

    return response()->json(['success'=> $success], $this->successStatus);

My error Log

No authorization is needed. All your answers will be highly appreciated


Add this to your code

        public Map<String, String> getHeaders() throws AuthFailureError { 
                Map<String, String>  params = new HashMap<String, String>();  
                params.put("Content-Type", "application/json");
                params.put("Accept", "application/json");

                return params;
