codeSandbox examples for vtk.js gives error for controller.html

Pretty much the title. When I want to add the controller.html to my example in codesandbox, it gives error.

Cannot read properties of null (reading 'addEventListener')

So basically it doesn’t have document?

I couldn’t figure out why. Examples without controller works fine.

Can we have an official kitware/vtk codesandbox template that works and people can fork from it?

Thanks

Just rename controller.html to controller.txt and that will solve your issue.

That worked great!

My guess is that loading/importing an html asset was confusing to CodeSandbox while we only needed a string that could be injected as innerHTML somewhere…
