Production.log da error de método y Discourse no funciona

Soporte
1

Hola.

Hemos migrado nuestro Discourse a un nuevo servidor (Ubuntu 18.04 LTS desde 16.04). Pero la nueva instancia devuelve un error 500. En los registros de producción vi este mensaje:

NoMethodError (método suppress_from_latest' no definido para #<Category:0x00007fe51548abf0>) /var/www/discourse/vendor/bundle/ruby/2.6.0/gems/activemodel-5.2.3/lib/active_model/attribute_methods.rb:430:in method_missing’

El Modo Seguro no funciona. Tampoco funciona la reconstrucción.

Gracias por la ayuda.

¿Puedes compartir todo el rastreo? Esto parece ser un plugin antiguo incompatible que necesita ser eliminado.

GitHub - discourse/plugin_discourse_dynamic_sidebar · GitHub es un plugin conocido por estar roto y que causa ese error.

3

Hola,

Solo tenemos tres plugins:
- git clone GitHub - discourse/discourse-spoiler-alert: A plugin for discourse to hide spoilers behind the spoiler-alert jQuery plugin · GitHub
- git clone GitHub - discourse/discourse-cakeday: Show a birthday cake emoji beside the names of members on their join anniversary, or their actual birthday -- and a browsable directory of upcoming anniversaries / birthdays. · GitHub
- git clone GitHub - discourse/discourse-adplugin: Official Discourse Advertising Plugin. Install & Start Serving Ads on Your Discourse Forum · GitHub

Pero creo que, si el problema es causado por los plugins, el sitio debería funcionar en modo seguro. ¿Estoy equivocado?

4

Sí, estás equivocado. El modo seguro afecta solo a la aplicación del front-end (JS + CSS) y no tiene nada que ver con Ruby.

Como dije en mi respuesta anterior

¿Hiciste un

cd /var/discourse
git pull
./launcher rebuild app
7

No intenté hacer un git pull porque fue una instalación nueva.

Hi,

We’re also receiving this error. We installed new plugins to our forum and then received these errors once the forum booted. None of the plugins we installed referenced the method in the error and we also tested these plugins on a test environment without any issues.

EDIT: As of 2:29 PM GMT, we have managed to get our forum back up and running - our team is looking into the root cause.
