如何修复python folium geoJSON代码中的“AttributeError：'str'对象没有属性'setdefault'”？

如何让 folium 接受似乎导致此错误的 geoJSON 输入？

尝试制作等值线地图并遇到相同的错误，因此尝试仅使用我通过获取较大 geoJSON 文件的子集创建的 JSON 文件在基本大叶地图上进行 geoJSON 覆盖。在 Juypter Notebook 中工作。JSON 文件似乎具有正确的结构。

msp_map = folium.Map(location=[纬度，经度]，zoom_start=10)

folium.GeoJson(msp_zipcode_geo, name='geojson').add_to(msp_map)

msp_map

期望获得带有 geoJSON 文件中指定的县边界覆盖的地图。
