PHP, Symfony docker / FastCGI sent in stderr: "Primary script unknown"

Cześć, chciałem sobie podstawić Symfony na dockerze, W konsoli build printuje mi: FastCGI sent in stderr: "Primary script unknown" while reading response header from upstream.

mój config:

docker-compose.yml

version: '3.1'
services:
    mysql:
        image: 'mysql:8.0'
        working_dir: /app
        volumes:
            - '/api:/app'
        environment:
            - MYSQL_ROOT_PASSWORD=secret
            - MYSQL_DATABASE=ecom
            - MYSQL_USER=user
            - MYSQL_PASSWORD=secret
        ports:
            - '8082:3306'

    webserver:
        image: 'nginx:alpine'
        working_dir: /app
        volumes:
            - '/api:/app'
            - './phpdocker/nginx/nginx.conf:/etc/nginx/conf.d/default.conf'
        ports:
            - '8080:80'

    php-fpm:
        build: phpdocker/php-fpm
        working_dir: /app
        volumes:
            - '/api:/app'
            - './phpdocker/php-fpm/php-ini-overrides.ini:/etc/php/8.1/fpm/conf.d/99-overrides.ini'

nginx.conf

server {
    listen 80 default;

    client_max_body_size 108M;

    access_log /var/log/nginx/application.access.log;

    root /app/public;
    index index.php;

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

    if (!-e $request_filename) {
        rewrite ^.*$ /index.php last;
    }

    location ~ \.php$ {
        fastcgi_pass php-fpm:9000;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        fastcgi_param PHP_VALUE "error_log=/var/log/nginx/application_php_errors.log";
        fastcgi_buffers 16 16k;
        fastcgi_buffer_size 32k;
        include fastcgi_params;
    }
}

Dockerfile php-fpm

FROM phpdockerio/php:8.1-fpm
WORKDIR "/app"

RUN apt-get update; \
    apt-get -y --no-install-recommends install \
        php8.1-mysql; \
    apt-get clean; \
    rm -rf /var/lib/apt/lists/* /tmp/* /var/tmp/* /usr/share/doc/*

Struktura plików:

- api (czyste symfony)

- phpdocker

     - nginx

     - php-fpm

- docker-compose.yml

Po wejściu na localhost:8080 dostaje 

File not found.

A w konsoli bo build printuje mi
