Code only extracts header but doesn't extract data

[map06]

I need to extract data for weather stations across Asia. I tried installing and running it as said in the README file. However, for some reason, the code is not extracting the data but is only extracting the headers. I don't get any error.

What are the links you added to the file? Did you make sure there is data available on those stations in the date range you provided ?

For example one of the link is
https://www.wunderground.com/dashboard/pws/IGURUG1

This is my settings,

from datetime import date

# Set Date format like: YYYY, MM, DD
# Note that FIND_FIRST_DATE uses START_DATE as default start date
START_DATE = date(2018, 1, 1)
END_DATE = date(2020, 7, 19)

# set to "metric" or "imperial"
UNIT_SYSTEM = "metric"
# UNIT_SYSTEM = "imperial"

# Automatically find first date where data is logged
FIND_FIRST_DATE = True
                          

When I run:
python3 weather_scraper.py:
It prints:

When I check IGURUG1.csv
It only has :

Date,Time,Temperature_C,Dew_Point_C,Humidity_%,Wind,Speed_kmh,Gust_kmh,Pressure_hPa,Precip_Rate_mm,Precip_Accum_mm,UV,Solar_w/m2

I checked the website. It does have data for specified date.
