ERR#0015: error 429, try again later. on investpy.get_fund_historical_data method

[technqvi]

Hi

I use investpy to retrieve the fund price as in the code below.
I experience error as earlier mentioned in the subject.
ERR#0015: error 429, try again later.

1. How to tackle this problem?
2. How many requests to retrieve data a day ( 1 fund / 1 request)?

`
import investpy
import datetime
import pandas as pd
path=r'D:\AB_DB\AB_Fund_World_Files'

#fund_name='Polar Capital Funds Plc - Polar Capital Global Technology Fund I Income'
today_str=datetime.date.today().strftime('%d/%m/%Y')
print(today_str)
fund_name='Tmb China Opportunity Retirement Mutual Fund'
country_name='thailand'
#Ireland Luxembourg united Kingdo
try:
df = investpy.get_fund_historical_data(fund=fund_name,
country=country_name,
from_date='20/03/2022',
to_date=today_str)
print(df.head())
except Exception as ex:
print(ex)

#df.to_csv(f'{path}\{fund_name}.csv',index=True)

The figure below shows actual script that I use to retrieve fund ata
There are around 50 funds on a daily basis
