IndexError: index 0 is out of bounds for axis 0 with size 0

Describe bug

yfinance returns incorrect timeseries dates for ticker CADUSD=X when start date is 2024-09-02. Sep 3rd is basically returned as Sep 4th. Additionally, when using start date as 2024-09-03 the program crashes.

Simple code that reproduces your problem

import datetime as dt
import yfinance as yf

ticker = "CADUSD=X"
obj = yf.Ticker(ticker)
start = dt.date(2024, 9, 3)

df = obj.history(start=start)
