Try to open the Inspector using NextJS but it said [ERR_REQUIRE_ESM]

I’ve imported the package directly following the docs.

import "@babylonjs/core/Debug/debugLayer";
import "@babylonjs/inspector"

Then it shows err message below:

require() of ES Module E:\XXX\next-babylonjs1\node_modules\@babylonjs\core\index.js from E:\XXX\next-babylonjs1\node_modules\@babylonjs\inspector\dist\babylon.inspector.bundle.max.js not supported.
Instead change the require of index.js in E:\XXX\next-babylonjs1\node_modules\@babylonjs\inspector\dist\babylon.inspector.bundle.max.js to a dynamic import() which is available in all CommonJS modules.

The inspector package is still not fully esm compatible. We will take care of that as part of the future esm package work. Sorry 'bout that, I don’t have a good solution for that at the moment

:smiley:OK,Thank you~

Hi, I just came across this issue and have used a dynamic import of a custom component.
Probably not a great solution but seems to work around the ESM issue for local debugging, etc.

Main page where I want to use the debugger:

// set the scene on sceneReady call
let sceneRef = useRef<Scene | null>(null);

// dynamic import of the custom component
const Debugger = dynamic(() => import("../components/Debugger"), {
  ssr: false,

// in my return render of page
 <Debugger sceneRef={sceneRef} />

My custom component:

import { Scene } from "@babylonjs/core";
import { MutableRefObject } from "react";
import "@babylonjs/core/Debug/debugLayer";
import "@babylonjs/inspector";

const Debugger = ({
}: {
  sceneRef: MutableRefObject<Scene | null>;
}) => {
  if (sceneRef.current) {;
  return <></>;

export default Debugger;

Probably late to the conversation to help @fansticB now, but just in case anyone else runs into this :slight_smile:

import(“@babylonjs/inspector”); instead of
import “@babylonjs/inspector”;

@11128, yep! much simpler :slightly_smiling_face: !
Although I needed to await the import

As an update to what I posted originally, remove the custom component and have a function call to dynamically import the inspector module (and display the debugger) at the bottom of my onSceneReady function.

Main page where I want to use the debugger

import "@babylonjs/core/Debug/debugLayer";
  const runDebugger = async (scene: Scene) => {
    await import("@babylonjs/inspector");;


const onSceneReady = async (scene: Scene) => {
 await runDebugger(scene);

Thanks for sharing your solution!
