Network declared as external, but could not be found

Hi,

I am trying to create a container that allows a database connection from another docker container so that I can import data. This is my docker-compose.yaml

version: '3'
services:
    main:
        build:
            context: ./vendor/laravel/sail/runtimes/8.1
            dockerfile: Dockerfile
            args:
                WWWGROUP: '${WWWGROUP}'
        image: sail-8.1/app
        extra_hosts:
            - 'host.docker.internal:host-gateway'
        ports:
            - '${APP_PORT:-80}:80'
            - '${VITE_PORT:-5173}:${VITE_PORT:-5173}'
        environment:
            WWWUSER: '${WWWUSER}'
            LARAVEL_SAIL: 1
            XDEBUG_MODE: '${SAIL_XDEBUG_MODE:-off}'
            XDEBUG_CONFIG: '${SAIL_XDEBUG_CONFIG:-client_host=host.docker.internal}'
        volumes:
            - '.:/var/www/html'
        networks:
            - main
            - search
        depends_on:
            - mysql
    mysql:
        image: 'mysql/mysql-server:8.0'
        ports:
            - '${FORWARD_DB_PORT:-3306}:3306'
        environment:
            MYSQL_ROOT_PASSWORD: '${DB_PASSWORD}'
            MYSQL_ROOT_HOST: "%"
            MYSQL_DATABASE: '${DB_DATABASE}'
            MYSQL_USER: '${DB_USERNAME}'
            MYSQL_PASSWORD: '${DB_PASSWORD}'
            MYSQL_ALLOW_EMPTY_PASSWORD: 1
        volumes:
            - 'sail-mysql:/var/lib/mysql'
            - './vendor/laravel/sail/database/mysql/create-testing-database.sh:/docker-entrypoint-initdb.d/10-create-testing-database.sh'
        networks:
            - main
        healthcheck:
            test: ["CMD", "mysqladmin", "ping", "-p${DB_PASSWORD}"]
            retries: 3
            timeout: 5s
networks:
    search:
        external:
            name: search
    main:
        driver: bridge
volumes:
    sail-mysql:
        driver: local
    sail-redis:
        driver: local
    sail-meilisearch:
        driver: local

When I run sail compose I get the following error:

WARN[0000] network search: network.external.name is deprecated in favor of network.name 
WARN[0000] network search: network.external.name is deprecated in favor of network.name
