plotly animation on scattermapbox frame

Question

I actually had this working for me for a minute, but now I can't figure out how to get back to working form.

For the animation (Plotly/Python), my question is around the frame . What is the correct format for each frame when it should be rendered as an animation when it is a 'scattermapbox'? I think that's where stuff is going wrong for me.

I'm borrowing code from here - https://plot.ly/~empet/14825/scattermapbox-animation-forum-question/#/

This same code works fine with just running this figure without the animation. After set the data and layout variables - this works

---

fig = dict(data=data, layout=layout)
py.iplot(fig, filename='MultipleMapbox')

---

However, when I run the code below, I get an error. Here's the full code -

              sliders=sliders)
fig=dict(data=data, layout=layout, frames=frames)
plot(fig)

The error value I'm getting is

ValueError: Invalid properties specified for object of type plotly.graph_objs.Scatter: ('lat', 'lon')

Looks like the Frame element doesn't like the 'lat' 'lon', and that's where I'm stuck.
