Error INVALID_OPERATION: drawElements ?

[Dad72]

I have a error in the console that i don't understand. What is this error? 

 

Error in Google Chrome
 

256 WebGL: INVALID_OPERATION: drawElements: attribs not setup correctly                                            babylon.js:2
WebGL: too many errors, no more errors will be reported to the console for this context.

this function :

BABYLON.Engine.prototype.draw = function (useTriangles, indexStart, indexCount) {        this._gl.drawElements(useTriangles ? this._gl.TRIANGLES : this._gl.LINES, indexCount, this._gl.UNSIGNED_SHORT, indexStart * 2);};

Or

(function() {with (this[2]) {with (this[1]) {with (this[0]) {return function(event) {SelectedMesh("Modeles/Rabbit/", "Modeles", "Rabbit.babylon");};...}}}})

Error In Firfox :

I did not have this problem with previous versions .

Should come from your side. Everything is working on the website or on my computers

Yes I managed to find the problem. If i wrote:

function init(CheminModeles, Fichier, Name){    engine = new BABYLON.Engine(container, true);    scene = new BABYLON.Scene(engine);     BABYLON.SceneLoader.ImportMesh(Name, CheminModeles, Fichier, scene, function (newMeshes, particleSystems, skeletons){        modele = newMeshes[0];    }); } function SelectedMesh(chemin, dossier, meshe){    if(modele){        modele.dispose();    }     init(CheminModeles, Fichier, Name);}

I had some errors because of  modele = newMeshes[0];

 

if i delete :

    modele = newMeshes[0];

and 

    if(modele) {
        modele.dispose();
    } 

 

not error.

 

I don't know why.
