I have been using Paraview glance successfully for the past many months. Today I started getting this error when manually uploading my vtu file.
“import object field ‘invoke\_vii’ is not a Function”
I am attaching my sample vtu file that gives the error.

Your attached dataset loads for me. Can you clear the browser cache on reload and try again? (This is usually achieved with ctrl-shift-R.)

Thanks, yes it seems to be working now. Probably was some temporary glitch or something…
