Hi guys~!! I am having issues with opening/using Babylon with Chrome for some reason ☹ [1]. My current project is not loading I have downloaded babylon module with npm, but I found out that unless I use dracoCompression, it will always try to pull from [preview.babylon.com](http://preview.babylon.com) [[post - https://forum.babylonjs.com/t/draco-decompression-broken/14789](https://forum.babylonjs.com/t/draco-decompression-broken/14789)] ![Screen Shot 2021-08-11 at 5.28.35 PM](https://us1.discourse-cdn.com/flex024/uploads/babylonjs/original/3X/7/a/7ad0514ed4ef27bd367018517c2a0cce4e050b66.jpeg) [2]. More surprisingly, I cannot even open Babylon PlayGround ☹ [link to the PG](https://playground.babylonjs.com/#UU7RQ#1) ![Screen Shot 2021-08-11 at 5.25.26 PM](https://us1.discourse-cdn.com/flex024/uploads/babylonjs/original/3X/c/4/c493439054b26d5f604c6bbdb000e6a1841ed392.png) ![Screen Shot 2021-08-11 at 5.31.13 PM](https://us1.discourse-cdn.com/flex024/uploads/babylonjs/original/3X/5/0/50506af3d946db289347fa323d78c2ff77881c18.png) Another surprise. I can still open my project, PG, and everything using other browsers like Safari or even on mobiles, but just not on my computer… Does anyone know what is going on? Thanks! Have a happy coding day~! ---

Is there anyone else who has been having problems with the playground? ---

@Faber PlayGround and my project are all working now. I want to prevent this from happening though. It seems like [THIS](https://doc.babylonjs.com/typedoc/classes/babylon.dracocompression#configuration) is the way to do so. As far as I know, Draco is a way of compressing .gltf and to load a .gltf model, I need this draco thingy. What happened to me was because my project was trying to pull draco file that is required to load .gltf, but because it is not internally located in my project, in an attempt to pull it from [preview.babylon.com](http://preview.babylon.com), there was an error. Is this correct? How can I put it in my project so that it won’t happen again?? Where should this go? ![Screen Shot 2021-08-11 at 7.06.06 PM](https://us1.discourse-cdn.com/flex024/uploads/babylonjs/original/3X/6/f/6f4f97589fab6c3ab5ddf67e8ff4be564b8779e4.png) ![Screen Shot 2021-08-11 at 7.21.02 PM](https://us1.discourse-cdn.com/flex024/uploads/babylonjs/original/3X/3/d/3d7152cf025c8a4509737a450b105ef12926e7ce.png) I just included this in the code block where I am declaring and initiating the engine, scene, canvas, camera, etc. before loading .gltf Would this be the right way? Thank you for your help! ---

Hi! I’m sorry that you lost 2-week worth work. Really sorry to hear that. Hope you are now back on track. Yes I am Korean. Are you currently working in some other country? ---

Did you somehow figure out how to prevent this error? It seems like [THIS](https://doc.babylonjs.com/typedoc/classes/babylon.dracocompression#configuration) is the way to do so, but I am not sure how I can work it out ☹ ---

DracoComperssion.Configuration is a static object that you can change: [Babylon.js Playground (babylonjs.com)](https://playground.babylonjs.com/#FVUGVM) (line 29) If you import DracoCompression (in case you are using es6 imports) it will work the same ---

So I can just do this? ```auto DracoCompression.Configuration.decoder.wasmUrl = `some location of wasm file in my project` ``` ---

i would guess the first line is the important one. You are loading the .js file as a text/html (might be a 404?) so it can’t execute it. it should be application/javascript ---

hmm it’s already a js file though. Wouldn’t writing a relative path to the wasm file work? ☹ ---

the fact that it is .js is good, but your server is sending it incorrectly. and the browser can’t import this script for that reason. This is at least what the error message is saying ---

it’s really hard helping without knowing anything about your project. If you want to reproduce this on the playground, we will be able to debug this with you. ---

I am trying to reproduce the problem on PlayGround, but I don’t see the draco url request on the PG like my project does. How come the PG can use .gltf without draco thingy??
