Hi, I have a problem with babylonjs and angular, when I run the ng serve command this errors appears: ![errsa](https://us1.discourse-cdn.com/flex024/uploads/babylonjs/original/3X/f/2/f2c7e280c96a0596c7c9158504f68db2ae75b08d.png) I can´t resolve. ---

Hello and welcome to the Babylon.js forum! Can you share a link to your project? ---

I think @RaananW fixed this recently and it requires the latest typescript version. @RaananW please correct me if I am wrong 🙂 ---

This was just updated, but shouldn’t have caused any issues, even with old(er) versions of typescript. At least not the last 2-3 minor versions. Did it work until now? Or is it the first time you are trying to do that? I also find it a little odd that this is reported from engine.d.t and not webxr.d.ts . Can you share a reproduction? ---

I started the project yesterday, and still i can´t fix, I want to integrate babylonjs into an angular project, I already update typescript version in Angular and babylon to 4.8.2 and still this errors appears. ---

I see the same string of errors. I can’t share any code because we’re using BabylonJS in a major product configuration tool, it isn’t something I can just paste into a playground example. 5.29.0 works with Typescript 4.8.4 as long as my Angular packages are all 14.2.2 and 14.2.3. Once the Angular packages get updated, I see the same errors shown above. ---
