Gracias por tu respuesta, actualicé a la versión 3.1.2, pero la página recibida en el navegador está en blanco. Una nota, está instalado sobre kubernetes. Aquí está el registro:

Parece que el plugin discourse-local-dates fue el culpable. Una vez que lo deshabilité, todo comenzó a funcionar. Tendré que ver cómo puedo volver a poner este plugin.
Francamente, estoy un poco perdido. No sé qué pasó, realicé una actualización con kubectl. La actualización tuvo que usar una versión anterior de postgres (por defecto, la 16 se instala con el último chart, lo cual no es bueno para discourse 3.1.2). No hubo errores, pero esa página en blanco, y después de mover discourse-local-dates todo salió bien, y no más errores en la consola del navegador.
