Frankenphp continuously sending requests to / in docker container

What happened?

I'm new to Franken, trying to set it up for the first time and running Franken as a docker container and each time I run it I see in docker logs that it is continuously sending requests to / and failing with 404 as I do not have such a route

{"message":"request_exception","context":{"exception_class":"Symfony\\Component\\HttpKernel\\Exception\\NotFoundHttpException","exception_message":"No route found for \"GET http:///index.php/\"","exception_status":404,"exception_trace":

and it sends those requests one after another, but I did not trigger any requests at all.

(shortened version of Dockerfile)

FROM dunglas/frankenphp:1.2-php8.2-alpine as base

ADD https://github.com/mlocati/docker-php-extension-installer/releases/latest/download/install-php-extensions /usr/local/bin/

RUN chmod +x /usr/local/bin/install-php-extensions && sync && install-php-extensions \
    @composer \
    apcu-stable \
    intl-stable \
    opcache-stable \
    pcntl-stable \
    pdo_pgsql-stable \
    pgsql-stable \
    redis-stable \
    zip-stable;

FROM base as common

COPY ../composer.lock /src/app/composer.lock

WORKDIR /src/app/

FROM common as test

COPY --chown=daemon:daemon frankenphp/caddy/Caddyfile /etc/caddy/Caddyfile <--- copy Caddy config
COPY --from=common --chown=daemon:daemon /src/app/ /src/app
COPY --chown=daemon:daemon .. /src/app/

RUN install-php-extensions \
   pcov-stable  \
   xdebug-3.2.2;

RUN cp ${PHP_INI_DIR}/php.ini-development ${PHP_INI_DIR}/php.ini

USER daemon:daemon

RUN composer install \

   -d tools;

RUN composer install \
   --no-interaction \
   --no-progress \
   --verbose; \
   composer run-script install-codestandards

USER root:root

my Caddyfile looks like this:

{
    {$CADDY_GLOBAL_OPTIONS}

    frankenphp {
        worker public/index.php
    }

    auto_https off
}

{$CADDY_EXTRA_CONFIG}

api.localtest.me {
    root * public/
    encode zstd br gzip

    {$CADDY_SERVER_EXTRA_DIRECTIVES}

    php_server
}

in my docker-compose service described like:

api-frankenapp:
    build:
      context: ./src/app
      dockerfile: ./frankenphp/Dockerfile
      target: test
      args:
        - COMPOSER_AUTH=$COMPOSER_AUTH
    container_name: api_frankenapp
    volumes:
      - ./src/products-data-api/:/srv/app/:rw
      - api-app-cache:/src/app/var/cache
      - api-app-assets:/src/app/public/bundles
    expose:
      - 80
    networks:
      default:
        aliases:
          - api.local.me

Anf of course, I have installed runtime/frankenphp-symfony . What I'm doing wrong here? why right after I run the image it immediately start sending requests? Thanks in advance!
