Been trying to implement this code

```py
fg.add_child(folium.GeoJson(data=(open("12.1 world.json", "r", encoding="utf-8-sig")).read()))

```

Gives me the Error: `Extra data: line 1 column 2108737 (char 2108736)`

Tried this:

```py
import json
with open('12.1 world.json',encoding="utf-8-sig",errors='ignore') as f:
    data = [json.loads(line,strict=False) for line in f]

```
