Issue in medium-mslp-rain notebook

What happened?

I tried the medium-mslp-rain.ipynb notebook with Binder, and when computing the total precipitation between steps 12 24 UTC it returns a TypeError:

---------------------------------------------------------------------------

    466 df = df.sort_values("_msgIndex1")
    467 df = df.rename(columns={"_msgIndex1": "Message"})

TypeError: 'NoneType' object is not subscriptable

What are the steps to reproduce the bug?

Run the notebook with Binder as is.

plotting error

Hi there,
I am a new Bee and trying to plot ecmwf forecast chart using the notebook script for 850 Temp and 500 Geopotential height, but getting the following error. I already downloaded the api key and code runs fine until it comes to the plotting functions where i get the following errors,

Any help in fixing the error will be greatly appreciated.

Cheers,
Basit
