Почему мой файл docker-compose.yml не находит мой файл Dockerfile*end

Я пытаюсь запустить docker-контейнер из моего файла docker-compose:

    version: '3'
    
    services:
      memory_Backend:
        build:
          context: ./
          dockerfile: ./project/docker/DockerfileBackend
        image: memoryapi_ad_img
        volumes:
          - ./:/var/lib
        ports:
          - 15555:25555
    
      memory_Frontend:
        build:
          context: ./
          dockerfile: ./project/docker/DockerfileFrontend
        image: memorywebsite_ad_img
        volumes:
          - ./:/var/lib
        ports:
          - 15556:25556

но это дает мне

ошибка

Но мои DockerfileFrontEnd и DockerfileBackEnd находятся в /project/docker/

а ещё они выглядят вот так

    FROM demers/python420w4a
    COPY ./requirements.txt /
    RUN pip3 install -r /requirements.txt
    RUN apt-get update -y
    RUN apt-get install -y xxd
    WORKDIR /var/lib
    CMD ["./run.sh", "./project/main/memoryapi.py", "25555"]

и мой DockerfileFrontEnd:

    FROM demers/python420w4a
    COPY ./requirements.txt /
    RUN pip3 install -r /requirements.txt
    RUN apt-get update -y
    RUN apt-get install -y xxd
    WORKDIR /var/lib
    CMD ["./run.sh", "./project/app/memoryfront.py", "25556"]

также мой файл startDocker.sh:

    #!/bin/bash
    
    vol_name=memory_ad_vol
    api_cont_name=memoryapi_ad_cnt
    api_image_name=memoryapi_ad_img
    website_cont_name=memorywebsite_ad_cnt
    website_image_name=memorywebsite_ad_img
    
    echo "Début du lancement de l'api et du Site Web dans Docker"
    echo "Le nom pour l'image de l'api: $api_image_name"
    echo "Le nom pour l'image du Site Web: $website_image_name"
    echo "Le nom du volume où vont ce trouver les images et conteneurs: $vol_name"
    echo "Le nom pour le conteneur de l'api: $api_cont_name"
    echo "Le nom pour le conteneur du Site Web: $website_cont_name"
    
    ###CLEANUP
    echo "Stoping everything"
    docker-compose -f docker-compose.yml --project-directory . down
    
    
    ###REBUILD
    echo "Creating everything"
    docker-compose -f docker-compose.yml --project-directory . up -d

и, наконец, вот мой файл run.sh

    #!/bin/bash
    
    export PYTHONPATH=$PWD/project/
    echo python path is: 
    echo $PYTHONPATH
    
    echo "Launching program"
    echo $@
    python3 "$@"

Заранее спасибо за помощь, пусть и минимальную!

Информация Редактировать 1:

1. я нахожусь в каталоге /tp4startingpoint/ в моей виртуальной машине Linux
2. я не использую docker-compose напрямую, а использую свой скрипт ./startDocker.sh, чтобы сделать всю работу за меня.
