v2.2.4: How to fix the error Tracking Address function doesn't work?

QUESTION:

We have installed version 2.2.4 on my site Magento 2.3.5_p1

The module has Google address auto-complete function. We have created an API and entered it in the one-page checkout BSS backend setting. After update and deployment and clearing the cache the address auto-complete seems not to work.

ANSWER: 

To fix this error, please  add file Bss/OneStepCheckout/etc/csp_whitelist.xml as below:

<?xml version="1.0"?>
