Few questions about setting Caddy with yourls-fpm

[NagaseYami]

First of all, sorry for my poor english.
What I'm saying is maybe a little "Google".

I'm new to the PHP and Caddy.
And I'm trying to add YOURLS to my server.
I want to use a existed Caddy because there are some web service is already runing.

https://caddy.community/t/v2-help-to-set-up-a-yourls-instance/7260
https://caddy.community/t/example-yourls/7908
I checked out these pages and I made a docker-compose.yaml & Caddyfile like these.

version: "3.9"
services:
  mysql:
    image: mysql
    container_name: mysql
    restart: always
    environment:
      - MYSQL_ROOT_PASSWORD=somepass
      - MYSQL_DATABASE=somedbname
      - MYSQL_USER=someuser
      - MYSQL_PASSWORD=somepass
    volumes:
      - ./mysql:/var/lib/mysql
  
  yourls:
    image: yourls:fpm-alpine
    container_name: yourls
    restart: always
    environment:
      - YOURLS_DB_HOST=mysql:3306
      - YOURLS_DB_NAME=somedbname
      - YOURLS_DB_USER=someuser
      - YOURLS_DB_PASS=somepass
      - YOURLS_SITE=https://yourls.domain.com
      - YOURLS_USER=someuser
      - YOURLS_PASS=somepass
    depends_on:
      - mysql

  caddy:
    image: caddy:alpine
    container_name: caddy
    restart: always
    ports:
      - "80:80"
      - "443:443"
    volumes:
      - ./caddy/Caddyfile:/etc/caddy/Caddyfile:ro
      - ./caddy/data:/data
      - ./caddy/config:/config
    depends_on:
      - yourls

{
    debug
    email   [email protected]
}

https://yourls.domain.com {
    root * /var/www/html
    route {        
        try_files {path} {path}/index.php yourls-loader.php
        php_fastcgi yourls:9000
    }
    file_server
}

It works. But a little weird.
It can't automatically redirect to yourls-loader.php or index.php when I access https://yourls.domain.com or https://yourls.domain.com/admin/.
And all asset and javascript can't be load. Here is a part of caddy log when I try to load common.js.
