Cannot add new country to CountryMap chart

[barmic12]

I was trying add new country following to https://superset.apache.org/visualization.html#need-to-add-a-new-country, however it doesn't work - new country is visable in dropdown, but when I click on it, map is blank.

Expected results

Can display new added map from .geojson

Actual results

I get 404 when I click new country on dropdown map is fetching:

Request URL: http://localhost:5000/superset/explore/undefined
Status Code: 404 NOT FOUND

Other (default) maps works properly:

Request URL: http://localhost:5000/static/assets/dist/5f64d14062abb5f5fd6610972976ebe6.geojson
Status Code: 200 OK

I was able to resolve this issue by editing assets/node_modules/@superset-ui/legacy-plugin-chart-country-map/countries.js and add .geojson file to this directory. So it means that maps are fetched from npm package?

I needed to add a map and this was the only working way that I found.

It would be possible to have a way to add a new map instead of building it from source? There is some workaround?
