Bubble Maps (scattergeo) are not shown with geojson file

Iā€™m trying to create a scattergeo plot with geojson and featureidkey attributes (see following code), but the output is not what I expect. The markers are shown and the map defined in geojosn file is not shown.

import json
import pandas as pd
import plotly.express as px
import geopandas as gpd

with open('7001/Malaysia.geojson') as file:
    states = json.load(file)
vaccinated1 = pd.read_csv('7001/Vaccination Progress - 1st Vaccine Dose.csv')

fig1 = px.scatter_geo(vaccinated1.tail(16), geojson=states, locations="state",
                     featureidkey="properties.short",
                     color='percentage',
                     size="percentage",
                     center = {"lat": 6, "lon": 100.7129},
                     title = "Total vaccinated for 1st dose on {} (by Percentage)".format(vaccinated1.tail(16).iloc[0]['date']))
fig1.update_geos(fitbounds="locations", visible=False)
fig1.show()

What is missing in my example? Thanks in advance for your help
