A forum I help run was updated a few minutes ago, and chat seems to be unusable now (the UI for chat doesn’t show up, and attempting to use chat in tabs that haven’t been reloaded since the update results in an error).
Here’s an example of an error logged to /var/discourse/shared/standalone/log/rails/production.log when a chat API endpoint is accessed.
