ArcGIS Python Export Map to HTML is blank

#gis defined above using api key
map1 = gis.map('California, USA', zoomlevel=5)
map1

 This code produces this:

Using export_to_html(), the file is blank when opened in Firefox. When using embed, this is the result:

Forgive me for bumping an old topic, but I don't see a resolution in this thread. I'm having the same problem. 

I am using the Docker package with ArcGIS 2.2.0-python3.9. 

I'm unable to use the latest Docker package, for reasons I'll post in separate message.

I just tried to run the tutorial Saving ... a Map Widget in Google Colab, but I get the same result: a blank screen when I open the HTML file.
