Api-platform: Can't access files in directory /public/bundles/apiplatform (with nginx - fresh install)

[coolfarmer]

API Platform version(s) affected: 1.2.1

Description
I'm working on a new project and just installed apiplatform on it (in total I have 2 projects, one for the app and one for the API only), all work but when I'm going at _/api/contacts_ (for example), I get the page without any css/scripts. If I look into the logs I can see an error 404 on all resources inside /bundles/apiplatform.

nginx_1 | 172.18.0.1 - - [03/Dec/2019:20:35:24 +0000] "GET /bundles/apiplatform/style.css HTTP/1.1" 404 37396 "http://api.simtp.local:8785/api" "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:70.0) Gecko/20100101 Firefox/70.0"

Maybe an error in my nginx config but I passed the last 2 hours on this problem and I can't find the source of that problem.

Here is my docker-compose config:

version: '2'

services:
  nginx:
    image: 'bitnami/nginx:1.16'
    ports:
      - '8784:8080'

      - MYSQL_DATABASE=simtp
      - ALLOW_EMPTY_PASSWORD=yes
    networks:
      - default

networks:
  default:
    driver: bridge

And my conf file for nginx:

server {
    server_name api.simtp.local;
    root /app/simtp_api/public;
    listen 0.0.0.0:8081;

    location / {
        # try to serve file directly, fallback to index.php
        try_files $uri /index.php$is_args$args;
    }

    # optionally disable falling back to PHP script for the asset directories;
    # nginx will return a 404 error when files are not found instead of passing the
    # request to Symfony (improves performance but Symfony's 404 page is not displayed)
    # location /bundles {
    #     try_files $uri =404;
    # }

    location ~ ^/index\.php(/|$) {
        fastcgi_pass phpfpm:9000;
        fastcgi_split_path_info ^(.+\.php)(/.*)$;
        include fastcgi_params;

        # Increase the buffer size to handle large cache invalidation headers
        fastcgi_buffer_size 32k;
        fastcgi_buffers 32 4k;

        # optionally set the value of the environment variables used in the application
        # fastcgi_param APP_ENV prod;
        # fastcgi_param APP_SECRET <app-secret-id>;
        # fastcgi_param DATABASE_URL "mysql://db_user:db_pass@host:3306/db_name";

        # When you are using symlinks to link the document root to the
        # current version of your application, you should pass the real
        # application path instead of the path to the symlink to PHP
        # FPM.
        # Otherwise, PHP's OPcache may not properly detect changes to
        # your PHP files (see https://github.com/zendtech/ZendOptimizerPlus/issues/126
        # for more information).
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        fastcgi_param DOCUMENT_ROOT $document_root;
        # Prevents URIs that include the front controller. This will 404:
        # http://domain.tld/index.php/some-path
        # Remove the internal directive to allow URIs like this
        internal;
    }

    # return 404 for all other php files not matching the front controller
    # this prevents access to other php files you don't want to be accessible.
    location ~ \.php$ {
        return 404;
    }
}

If anyone can help me I'll be happy. Thanks!

I finally found the problem, forget to create the volumes in my nginx in docker-compose:

  nginx:
    image: 'bitnami/nginx:1.16'
    ports:
      - '8784:8080'
      - '8785:8081'
    networks:
      - default
    depends_on:
      - phpfpm
    volumes:
      - './simtp/public/simtp.conf:/opt/bitnami/nginx/conf/server_blocks/simtp.conf:ro'
      - './simtp_api/public/simtp_api.conf:/opt/bitnami/nginx/conf/server_blocks/simtp_api.conf:ro'
      - './simtp:/app/simtp:ro' # ---- THIS LINE IS THE SOLUTION ----
      - './simtp_api:/app/simtp_api:ro' # ---- THIS LINE IS THE SOLUTION ----
