history= game.history();
socket.emit('endgame', {'gameId':gameId,'player1':player1, 'player2':player2, 'winner': winner, 'history': history.toString(), note : checkLogout });
nodejsindex.js
var http = require('http').createServer().listen(4000);
var io = require('socket.io')(http);
var XMLHttpRequest = require('xmlhttprequest').XMLHttpRequest;
var xhttp = new XMLHttpRequest();
var host = 'localhost';
var port = '8000';
io.on('connection', function (socket) {
socket.on('endgame', function(msg){
var url = 'http://' + host +':' + port + '/save_game/';

Yourexceptblock is throwing away the error message, which probably contains useful information. Try this instead:except Exception as ex:, and thenprint("error saving game: %s" % ex)

@JohnGordon, that notice:[21/Nov/2018 23:40:59] "GET / HTTP/1.1" 200 1127 [21/Nov/2018 23:41:07] "GET /accounts/login/?next=/ HTTP/1.1" 200 446 [21/Nov/2018 23:41:10] "POST /accounts/login/?next=/ HTTP/1.1" 302 0 [21/Nov/2018 23:41:10] "GET / HTTP/1.1" 200 1127 error saving game: 'gameId' [21/Nov/2018 23:41:15] "POST /save_game/ HTTP/1.1" 200 7but nodejs notice successthe message was posted successfully

That error message seems to say thatmsg_objdoes not contain agameId. Try printingmsg_objbefore theGame.object.create()call.

@JohnGordon, gameId not here{'player1': 'han', 'player2': 'cat', 'winner': 'han', 'history': '[object History]', 'note': 'cat'} error saving game: 'gameId'and history not to convert to string
– Tran Quoc Gia Cat

Okay then, the error is obvious -- your caller is not supplying agameIdargument. How you handle that error is up to you.
