why after input .vtu file to vtureader inside of itk.js, then the vtkread inside of vtureader does not output any thing from my case

[peng_peter]

I use vue3+vite+typescript+@kitware/vtk.js+itk.js , then I input a .vtu file to vtu reader， I can see the vtu file that I input from rawDataBuffer, but the output is null, anyone can give me any help. thank you so much

itkPolyDataReader.parseAsArrayBuffer returns a promise. Are you awaiting this promise before getting the output?
