Oh, Sorry for the misleading, made a mistake with versions while building. I confirm that old version of web-project-templates/vue-vtkjs-pvw-template at master · Kitware/web-project-templates · GitHub works with vtk 9.0 and wslink 0.2.0 . Still have to check for updated server with vtk 9.1 and wslink >1.0.
Dear Sebastian,
Thank you so much for digging into it,
Best regards,
Evgeniya
