volumes for quick dev on docker compose don't work

Question

i create this docker-compose for my project (dev only) but for no particular reason on every OS the volume for ./back:/app and ./front:/app don't work (the other volumes work)

services:
  backend:
    build: ./back
    container_name: backend
    volumes:
      - ./back:/app
    ports:
      - "8080:8080"
    depends_on:
      - db
    networks:
      - back

  frontend:
    build: ./front
    container_name: frontend
    volumes:
      - ./front:/app
      - /app/node_modules
    ports:
      - "8900:5173"
    depends_on:
      - backend

  db:
    image: mysql:latest
    container_name: mysql_db
    environment:
      MYSQL_ROOT_PASSWORD: root
      MYSQL_DATABASE: gatekeeper
      MYSQL_USER: user
      MYSQL_PASSWORD: password
    ports:
      - "3308:3306"
    volumes:
      - mysql_data:/var/lib/mysql
    networks:
      - back

volumes:
  mysql_data:
networks:
  back:

detailled dockerfile for front and back front :

FROM node:latest

WORKDIR /app

COPY package*.json ./

RUN npm install -g vite

RUN npm install

COPY . .

EXPOSE 5173

CMD ["npm", "run", "dev"]

back:

FROM sapmachine:17

WORKDIR /app

COPY mvnw .

RUN chmod +x mvnw

COPY .mvn .mvn

COPY pom.xml .

RUN ./mvnw dependency:go-offline

COPY src ./src


EXPOSE 8080

CMD ["./mvnw", "spring-boot:run"]

actually the project build without any problem just the update of file from the computer to the docker don't work .
