+If you want to use your own `http_client` and wants to use `Reports` module, the `get_report_file` function follows a redirect URL from Checkout, 
+Ruby SDK uses `faraday-follow-redirects` which is an [open source](https://github.com/tisba/faraday-follow-redirects) solution that came after Faraday 2.0 deprecation, 
+you must add it otherwise Ruby SDK will not be able to download the contents file, or provide your custom redirect adapter.
