so anyone can help to solve this problem?

var scene;

document.addEventListener("DOMContentLoaded", startGame, false);
function startGame() {
    if (BABYLON.Engine.isSupported()) {
        canvas = document.getElementById("renderCanvas");
        engine = new BABYLON.Engine(canvas, false);

        BABYLON.SceneLoader.Load("Espilit/", "Espilit.babylon", engine, function (loadedScene) {
            scene = loadedScene;
   
            // Wait for textures and shaders to be ready
            scene.executeWhenReady(function () {
                // Attach camera to canvas inputs
                scene.activeCamera.attachControl(canvas);
                
                // Once the scene is loaded, just register a render loop to render it
                engine.runRenderLoop(function () {
                    scene.render();
                });
            });
        }, function (progress) {
            // To do: give progress feedback to user
        });

Hi and welcome. Here are a couple of topics that may help you. I found them by typing manifest in the forum search bar.

when i used

and

Espilit.babylon.manifest file

{
"version" : 1,
"enableSceneOffline" : true,
"enableTexturesOffline" : true
}

,browser showed

that's error.

Yes, I also have the impression that since some week, I notice that if I load a babylon file and I do not use a manifest file, the file is still cached, because if I modify the file and I reload it, it shows me the previous version of the babylon file.
I am obliged to empty the caches of the browser or use: file.babylon?' + (new Date()).getTime()

Can be a bug too.

It's then not a manifest error. Indeed, as specified before, you just need to set the boolean enableOfflineSupport to false and babylon.js will stop trying to do a XHR to test for the availbility of a .manifest file.

Your error seems to be linked to your node.js configuration. Have you set correctly the MIME type for .babylon file?

this my node.js code

var http = require('http'),
    path = require('path'),
    fs = require('fs'),

extensions = {                                                          //<--specify MIME file types.
    ".html" : "text/html",
    ".css" : "text/css",
    ".js" : "application/javascript",
    ".png" : "image/png",
    ".gif" : "image/gif",
    ".jpg" : "image/jpeg",
    ".babylon" : "application/babylon"                                   //<--- ADD .babylon MIME type.
};

//helper function handles file verification
function getFile(filePath,res,page404,mimeType){
    //does the requested file exist?
    fs.exists(filePath,function(exists){
        //if it does...
        if(exists){
            //read file and send response.
            fs.readFile(filePath,function(err,contents){
                if(!err){
                    res.writeHead(200,{
                        "Content-type" : mimeType,                      //<-- SET dynamic MIME TYPE.
                        "Content-Length" : contents.length
                    });
                    res.end(contents);
                }
            });
        }
    });
};

//handler for HTTP requests
function requestHandler(req, res) {
    var fileName = path.basename(req.url) || 'index.html',
        ext = path.extname(fileName),
        localFolder = __dirname + '/public/',
        page404 = localFolder + '404.html';

    if(!extensions[ext]){                                                //<-- CHECK file MIME type.
        //for now just send a 404 and a short message
        res.writeHead(404, {'Content-Type': 'text/html'});
        res.end("Not Found");
    };

    getFile((localFolder + fileName),res,page404,extensions[ext]);
};

http.createServer(requestHandler).listen(8008);

console.log('Node server is running on http://localhost:8008');
