plotly express line_mapbox() function shows nothing in .ipynb file on VSCode

[ShroXd]

hello, i tried to run the offical example in .ipynb file on VSCode, but the map was not showing up.
the version of plotly which i using is 4.2.1, and i had pass the mapbox token correctly.
other functions like scatter_polar() can correctly run.

here is the example: https://plot.ly/python/plotly-express/#maps

and here is the screenshot:

thank you
