The error doesn’t get into the log because it happens rails cranks up: ```plaintext root@test1-web-only:/var/www/discourse# rails c bundler: failed to load command: pry (/var/www/discourse/vendor/bundle/ruby/3.2.0/bin/pry) /var/www/discourse/vendor/bundle/ruby/3.2.0/gems/zeitwerk-2.6.7/lib/zeitwerk/loader/helpers.rb:135:in `const_get': uninitialized constant PluginInstance (NameError) parent.const_get(cname, false) ^^^^^^^^^^ Did you mean? PluginStore ``` I have replicated the error on another install. I’m trying to figure out which plugin it is right now. --- _[View the full topic](https://meta.discourse.org/t/no-errors-instance-not-coming-back-up-after-rebuild/257515)._
