Alaska by FIPS not appearing

Guise,

My fabulous choropleth map has but one shortcoming: Alaska data does not show. Thinking this might be a bug, perhaps a need to update a list in the plotly.express.choropleth library?

code (simplified):
fig = px.choropleth(

        filtered_df, geojson=counties, locations='fips',
        color='result',
        range_color=[0,1],
        color_continuous_scale=theColors,
        scope="usa",
        )

And here are some Alaska FIPS, which I know to be good:
02915
02933
02939

…which, as you can see from this OSM map, do indeed exist.
