Hi, i’m trying to use vtk.js with vue.js for 2D visualisation of 3D volumes. I tried calling `vtkGenericRenderWindow.newInstance()` in the `onMounted` hook of my component, but it would throw this error from inside the vtk.js implementation:

```auto
Uncaught TypeError: renNode is undefined
in traverse ForwardPass.js:43 (vtk.js implementation)

```

If you want to see how to connect a vtkRenderWindow into a view component, you can look at [that code](https://github.com/Kitware/vue-vtk-js/blob/master/src/core/VtkView.js).

Thank you! the issue turned out to be missing the `import @kitware/vtk.js/Rendering/Profiles/Volume`
