Getting empty result with get_historical_data

[grey949]

Summary (include Python version)

Python 3.9.7

For any stock symbol on 10/07/2021, I get an empty dataframe. However, if I place a range that includes 10/07/2021 I get that data. Here is what I'm seeing:

from iexfinance.stocks import get_historical_data

Using only 2021-10-07:
get_historical_data("TSLA", '2021-10-07', '2021-10-07', token="*********************")

Empty DataFrame
Columns: [close, high, low, open, symbol, volume, id, key, subkey, updated, changeOverTime, marketChangeOverTime, uOpen, uClose, uHigh, uLow, uVolume, fOpen, fClose, fHigh, fLow, fVolume, label, change, changePercent]
Index: []

Using a range to include 2021-10-7 will return data:
get_historical_data("TSLA", '2021-10-06', '2021-10-08', token="*********************")

        close    high     low    open symbol    volume                 id   key subkey        updated changeOverTime  ...   uHigh    uLow   uVolume   fOpen  fClose   fHigh    fLow   fVolume      label change changePercent

Having this issue again, but now noticing a pattern. Get_Historical_data() doesn't seem to work for any dates that are 5 days ago. For example, today is 10/17/2021 and now I can't run anything for 10/12/2021
