[Bug]: KeyError: 'label' when using df.mp.whois

Describe the bug Exception when running df.mp.whois

To Reproduce Steps to reproduce the behavior:

df.mp.whois(ip_column="ip")

I'm not sure of the IP address causing the exception, there's a large amount of IPs in the dataframe.

Expected behavior No exception :)
