getMeshUniformBuffer undefined

Bugs
1

I have a project that utilizes react-babylon. I recently updated react and all babylon related packages and I’m seeing some strange errors.

For example I am getting this error

Uncaught TypeError: mesh.getMeshUniformBuffer is not a function
    at StandardMaterial.bindForSubMesh (standardMaterial.js:1094:1)
    at Mesh.render (mesh.js:1641:1)
    at SubMesh.render (subMesh.js:300:1)
    at RenderingGroup._RenderSorted (renderingGroup.js:202:1)
    at RenderingGroup._renderOpaqueSorted (renderingGroup.js:148:1)
    at RenderingGroup.render (renderingGroup.js:97:1)
    at RenderingManager.render (renderingManager.js:118:1)
    at Scene._renderForCamera (ellipse.js:16:1)
    at Scene._processSubCameras (ellipse.js:41:1)
    at Scene.render (grid.js:95:1)

When I trace this in the dev tools I see that the mesh exists, but for some reason is missing the property getMeshUniformBuffer that it should have as defined in AbstractMesh

Here are my related packages
Before update:

        "@babylonjs/core": "^4.2.1",
        "@babylonjs/gui": "^4.2.1",
        "@babylonjs/loaders": "^4.2.1",
        "react": "^17.0.2",
        "react-babylonjs": "^3.0.31",

After update:

        "@babylonjs/core": "^5.33.0",
        "@babylonjs/gui": "^5.33.0",
        "@babylonjs/loaders": "^4.2.2",
        "react": "^18.2.0",
        "react-babylonjs": "^3.1.13",

I am using an .obj model and rendering it like this

import '@babylonjs/loaders/OBJ'
import { Model } from 'react-babylonjs'


        return <Model rootUrl={url} sceneFilename={name} onModelLoaded={loadComplete}/>

And this worked perfectly in the old package versions.

I’ve only done a bit of diving into the source to try and figure this out, maybe has something to do with the OBJ loader?

I was hoping someone could provide some insight into why this is happening, happy to provide additional information. Thanks!

This might be the issue as it should also be updated to 5.33

That did it!

Really thought I had updated that to the latest, stupid mistake.

Thank you for the quick reply.
