Erro on build yml file - network either does not exist

Alguem sabe porque o docker compose não consegue dar build e reconhecer minha network?

version: '3'

networks:
    tria-server-network:
        driver: bridge

services:
    postgres:
        build:
            dockerfile ./docker/postgres.dockerfile
            context:.
            image:tria-server/postgres
            container_name:tria-server-postgres
            ports:- "5432:5432"
            networks:- tria-server-network

    node:
        build:
            dockerfile ./docker/node.dockerfile
            context:.
            image:tria-server/node
            container_name:tria-server-node
            ports:- "4000:4000"
            networks:- tria-server-network
