如何修复JSON对象请求中的服务器错误500

Question

我正在编写一个Android应用程序，需要在其中使用后参数和自定义标头调用api，但我收到状态码为500的ServerError异常

private void checkLogin(final String email, final String password)
    {
        String url = "https://beta.talkhomeapp.com/auth/test/login";

        final String userpass = email+":"+password;

        RequestQueue rq = Volley.newRequestQueue(this);

        final ProgressDialog pd = new ProgressDialog(this);
        pd.setTitle("Login");
        pd.setMessage("Logging In");
        pd.show();

        JsonObjectRequest request = new JsonObjectRequest(JsonObjectRequest.Method.POST, url, null, new Response.Listener<JSONObject>() {
            @Override
            public void onResponse(JSONObject response) {
                Toast.makeText(MainActivity.this,"Success",Toast.LENGTH_LONG).show();
                pd.dismiss();
            }
        }, new Response.ErrorListener() {
            @Override
            public void onErrorResponse(VolleyError error) {
                Toast.makeText(MainActivity.this,error.getMessage(),Toast.LENGTH_LONG).show();
                pd.dismiss();
            }
        })
        {
            @Override
            protected Map<String, String> getParams() throws AuthFailureError
            {
                Map<String,String> params = new HashMap<>();
                params.put("email",email);
                params.put("Password",password);
                params.put("IPAddress","43.245.11.86");
                return params;
            }

            @Override
            public Map<String, String> getHeaders() throws AuthFailureError {
                Map<String,String> headers = new HashMap<>();
                headers.put("Authorization","Basic "+ Base64.encodeToString(userpass.getBytes(),Base64.DEFAULT) );
                return headers;
            }

            @Override
            public String getBodyContentType() {
                return "application/json";
            }
        };

                rq.add(request);
    }

如何在此应用程序中修复ServerError 500
