panel save not working with last bokeh and panel

[xavArtley]

after using pan.save('test.html') when I try to reload the file exported I get this error:

Can't reproduce this.

[xavArtley]

did you try with custom extension? Like :

import panel as pn
pn.extension('vtk')

dragon = pn.pane.VTK('https://raw.githubusercontent.com/Kitware/vtk-js/master/Data/StanfordDragon.vtkjs',
                     sizing_mode='stretch_width', height=400)
dragon.save('test.html')

Yes I did.

Oh right, I know what you mean now. Yes, I'm seeing the same thing.
