Error saving a mapbox element to png

Hello, recently the option of saving a fig with a mapbox element to a png file started to fail with the error:

ValueError: Transform failed with error code 525: Mapbox error.

The funny thing is that this exact same option worked just fine until a few days ago. The same error occurs when passing a mapbox token (even though the token is not mandatory for mapbox_style="open-street-map").

When trying to figure out what was the problem I reached this line in the source code, but I have no idea what is the solution.

Bellow a code block from the examples page that raises the same error:

import pandas as pd
us_cities = pd.read_csv("https://raw.githubusercontent.com/plotly/datasets/master/us-cities-top-1k.csv")

import plotly.express as px

fig = px.scatter_mapbox(us_cities, lat="lat", lon="lon", hover_name="City", hover_data=["State", "Population"],
                        color_discrete_sequence=["fuchsia"], zoom=3, height=300)
fig.update_layout(mapbox_style="open-street-map")
fig.update_layout(margin={"r":0,"t":0,"l":0,"b":0})

# fig.show()
fig.write_image('/tmp/test.jpg')

Using:
plotly.version: 4.14.3
kaleido.version: 0.2.1

Thank you.

Start with repos/kaleido/py/kaleido/scopes/base.py at line 308 and run the supplied Plotly Express reproduction using Plotly 4.14.3 and Kaleido 0.2.1. Compare the open-street-map case with and without a Mapbox token; done means fig.write_image succeeds for the reported example without the Mapbox error.
