"['geoCode'] not in index" when request CITY LEVEL interest_by_region Google trends
Hi, the pytrends API developers and maintainers,

Thank you for developing this great API and I'm now just starting to use it for my research. 
I recently ran into a key error when I tried to get Google treands data on city level.
My code is as follows:

import pandas as pd                        
from pytrends.request import TrendReq
pytrend = TrendReq()

kw_list=['Coronavirus']
pytrend.build_payload(kw_list, timeframe='today 3-m', geo='US', gprop='')
pytrend.interest_by_region(resolution='CITY',inc_low_vol=True, inc_geo_code=False)

**This is the error message.**
KeyError                                  Traceback (most recent call last)

   1186 
   1187             # we skip the warning on Categorical/Interval

KeyError: "['geoCode'] not in index"

I actually tried all API methods, and they worked very well, except for this one.

Thank you for your time!

Best,
Han
