Hi, I know that warnings are not bugs, but I am sharing this one because it appears frequently in our logs, I’m not able to identify whether it is coming from an extension, and it refers to an old Discourse version:
Deprecation notice: class_name field of EmbeddableHost has been deprecated. Prefer passing class_name as a parameter. (deprecated since Discourse 3.1.0.beta1) (removal in Discourse 3.2)
At /var/www/discourse/vendor/bundle/ruby/3.3.0/gems/activesupport-7.1.5/lib/active_support/callbacks.rb:403:inblock in make_lambda
The backtrace:
