I’ve been developing some plots based on the datashader case study. They are rendering and functioning well but I always get an error the first time the plot is shown. The plot is still rendered and interactive.
I thought it had to do with my implementation but it remains the same when I tried running the example.
f = go.FigureWidget(data=[{'x': x_range,
'y': y_range,
'mode': 'markers',
'marker': {'opacity': 0}}], # invisible trace to init axes and to support autoresize
layout={'width': plot_width, 'height': plot_height})
f
After I run the previous cell in that example this error is raised:

My plotly is at version 3.2.1
I don’t know how to check my plotly widget extensions jupyter nbextension list shows I have it enable but doesn’t show the version
