Problemas para habilitar CORS.

[alesan]

Hola a tod@s. He instalado Alfresco 7.0 a través de docker-compose y mi problema surge a la hora de hacer peticiones REST desde una pequeña aplicación externa que estoy desarrollando con Node.js y express. Podrían indicarme los pasos para habilitar cors?

Dejo la configuración del archivo docker-compose.yml y una captura de la respuesta al momento de hacer peticiones con fetch.

Desde ya muchísimas gracias.
