I am getting an error when switching from 7.22.5 to 7.49

BABYLON.SceneLoader.ImportMesh which I used in version 7.22.5 and then the onMeshLoaded method I ran gives an error in version 7.49

var hallLoader = BABYLON.SceneLoader.ImportMesh(
			"",
			env.STATICS_SERVER + "/assets/babylon5/hall_yeni/",
			"hall.gltf",
			this.sahne,
			(meshes) => {
				var scale = 100;
				meshes[0].scaling = new BABYLON.Vector3(scale, scale, -1 * scale);
  }
		);
hallLoader.onMeshLoaded = (mesh) => {
console.log(mesh)
}

The error message I encountered
↓↓↓↓
Uncaught (in promise) TypeError: Cannot set properties of undefined (setting ‘onMeshLoaded’)

Is this local? on the playground?

If it is local, did you update the loaders package as well?

No No, local of course.

CC @ryantrem , ImportMesh returns void now. was the signature different before?

Yes, when mime type support was added, it introduced new asynchrony in previously synchronous paths, and a breaking change was made to this API: Adding support to mimetype autodetection by deltakosh · Pull Request #15798 · BabylonJS/Babylon.js

You can do a similar thing with newer APIs though like this:

const assetContainer = await BABYLON.LoadAssetContainerAsync("https://raw.githubusercontent.com/BabylonJS/Assets/master/meshes/ufo.glb", scene, {
    pluginOptions: {
        gltf: {
            onMeshLoaded: (mesh) => {
                console.log(`Loaded mesh: ${mesh.name}`);
            },
        },
    },
});
assetContainer.meshes.forEach((mesh) => scene.addMesh(mesh));

Here is a PG for this: Babylon.js Playground
