Console error regarding SDK

Hello!

I’ve downloaded the plugin for Customer Chat a while ago, but only recently I’ve noticed a console error saying:
sdk.js:52
##########################
# The CustomerChat plugin will soon be removed from the main Facebook SDK.
# To continue using it please use the correct SDK URL.
# For more details see https://fburl.com/customer-chat-sdk
##########################

The link in the error is broken and I’m confused as to what causes this and what steps I should take to solve the error. There is no update available for the plugin so I am a bit at a loss.

Can you help out with advice?
Thank you!
