Parse Server 100 json server error code error

Question

I use this Parse Server Guide to create a local instance of the analysis server. I download and configure the example, and it works fine, but when I try to use the android SDK, I get this error

Here is my index.js

    // Example express application adding the parse-server module to expose Parse
// compatible API routes.

var express = require('express');
var ParseServer = require('parse-server').ParseServer;

var databaseUri = process.env.DATABASE_URI || process.env.MONGOLAB_URI

if (!databaseUri) {
  console.log('DATABASE_URI not specified, falling back to localhost.');
}

var api = new ParseServer({
  databaseURI: databaseUri || 'mongodb://localhost:27017/authens',
  cloud: process.env.CLOUD_CODE_MAIN || __dirname + '/cloud/main.js',
  appId: process.env.APP_ID || 'UBXrCTUXuXf6fEBpbE7sHBamq4b0RdQcASFTHxo9',
  masterKey: process.env.MASTER_KEY || 'ghFiFWGtdymY3oXqWDTDBz6RyW7XdMyWzjXoJjFb', //Add your master key here. Keep it secret!
  clientKey: '4m2WpkkGCX77w3FNq3JWT74nVgRKNsgTj10Q1s4t',
  //restAPIKey: 'b7gUiB4cI7JeKLqKCWCkTZbBX4YA9S7xlQuwmUqX',
  //javascriptKey: '0qBhikhxV8ZtM95o1zTLFhhiuuLGiwDVcTxyvNdw',
 // dotNetKey: 'rc0uYDFU3Bo5U24PlBxKMBX7GpsHj8QHJLLVgsFg',
});
// Client-keys like the javascript key or the .NET key are not necessary with parse-server
// If you wish you require them, you can set them as options in the initialization above:
// javascriptKey, restAPIKey, dotNetKey, clientKey

var app = express();

// Serve the Parse API on the /parse URL prefix
var mountPath = process.env.PARSE_MOUNT || '/parse';
app.use(mountPath, api);

// Parse Server plays nicely with the rest of your web routes
app.get('/', function(req, res) {
  res.status(200).send('I dream of being a web site.');
});

var port = process.env.PORT || 1337;
app.listen(port, function() {
    console.log('parse-server-example running on port ' + port + '.');
});

This is how I initialize

Parse.enableLocalDatastore(this);
    Parse.initialize(new Parse.Configuration.Builder(this)
            .applicationId(getString(R.string.parse_app_id))
            .clientKey(getString(R.string.parse_client_key))
            .server("http://10.0.3.2:1337/parse")
            .build());
    Parse.setLogLevel(Parse.LOG_LEVEL_VERBOSE);

as in the textbook. I use genymotion as my virtual device running in 10.0.3.2. Is there something that I don’t see or is it a common problem.

Update

If I use curl from cmd, it works fine

curl -X POST -H "X-Parse-Application-Id: UBXrCTUXuXf6fEBpbE7sHBamq4b0RdQcASFTHxo9" -H "X-Parse-Client-Key: 4m2WpkkGCX77w3FNq3JWT74nVgRKNsgTj10Q1s4t" -H "Content-Type: application/json" -d @json.txt http://localhost:1337/parse/classes/GameScore

Answer 1

I have found a solution. Instead of this

.server("http://10.0.3.2:1337/parse")

use this

.server("http://10.0.3.2:1337/parse/")

Answer 2

nodejs "/", "host: port/parse/". .
