Hi @noahbishop,

Can you give a bit more information?

• What Python version are you using?
• What version of folium?
• Do you get any error messages or warnings in Python?
• Do you see any error messages or warnings in your browser console?

What Python version are you using?

Python 3.7

What version of folium?

0.10.0

Do you get any error messages or warnings in Python?

None

Do you see any error messages or warnings in your browser console?

Uncaught TypeError: Cannot read property 'hasOwnProperty' of undefined
    at i.setStyle (leaflet.js:5)
    at i._setLayerStyle (leaflet.js:5)
    at i.<anonymous> (leaflet.js:5)
    at i.eachLayer (leaflet.js:5)
    at i.setStyle (leaflet.js:5)
    at TimeSliderChoropleth.html:120

The corresponding line in the html file is:

macro_element_e040a831450244af8b8cd9c49e72109f.setStyle(function(feature) {
                feature.properties.style;
            });

Thanks, that's helpful. Someone (possibly me) will have to look into this.

I've looked into it, the problem lies here.

I also see the exact same error.

Python 3.6.5
Folium 0.10.0

Errors are the same as noahbishop.

@noahbishop thanks for looking into this! That's a weird piece of code, it doesn't do anything as is. Do you want to open a PR with your fix?

https://github.com/python-visualization/folium/pull/1227 which fixes this issue has been merged.
