Chat - Unexpected error - 403 Exception

[Scrazzled]

I set everything up as instructed but when I attempt to use Chat I get unexpected errors. Logs show something about user agent not set but that isn't in any instruction anywhere so I don't know what it's expecting.

❌ Unexpected Error

Something went wrong. Please check the Chat logs in the Workbench Desktop App.

Go to the Workbench Desktop App tab
Click Output at the bottom left of the Project tab
Select Chat from the dropdown
Check the logs for more details
