Docker mounting rootfs caused not a directory error

Question

I've been trying docker-compose up -d to my container but causes this error below:

ERROR: for phpsample-feed_phpsample_1 Cannot start service phpsample: OCI runtime create failed: container_linux.go:346: starting container process caused "process_linux.go:449: container init caused \"rootfs_linux.go:58: mounting \\"/c/Users/testUser/Documents/phpsample-feed/src\\" to rootfs \\"/mnt/sda1/var/lib/docker/overlay2/e6bf66b01f587c8826c2944b676044c6a199a0c8c2b8807adf13de0e0f8c4509/ merged\\" at \\"/mnt/sda1/var/lib/docker/overlay2/e6bf66b01f587c8826c2944b676044c6a199a0c8c2b8807adf13de0e0f8c4509/ merged/var/www/html\\" caused \\"not a directory\\"\"": unknown: Are you trying to mount a directory onto a file (or vice-versa)? Check if the specified host path exists and is the expected type

Here is my docker-compose.yml file:

version: '3.7'
services:
  phpsample:
    build:
      context: .
    init: true
    ports:
      - '8080:80'
    depends_on:
      - db
      - redis
    volumes:
      - ./src:/var/www/html:rw
    environment:
      - DB_HOST=db
      - DB_USR=user
      - DB_PW=test
      - DB_DBNAME=phpsample
      - DB_DBPREFIX=dev_
      - IS_SHORT_URL=1
      - CACHE_DRIVER=redis
      - CACHE_HOST=redis
      - CACHE_PORT=6379
      - CACHE_REDIS_DB=3
      - DEBUG=false
    restart: always
  db:
    image: mysql:8
    environment:

  redis:
    image: redis:5-buster
    init: true
    command: ["redis-server", "--appendonly", "yes"]
    volumes:
      - redis_data:/data
volumes:
  db_data:
  redis_data:

My system and tools used:

Windows 10 Home
Docker Toolbox Terminal
Kitematic
Oracle VM

I've also tried editing my Shared Folders on VM by doing this. With the settings below:

Name: c/Users Path: C:\Users

Does src exist in the directory from which you are running docker-compose and is it a directory? — wobr
What if you change ./src:/var/www/html:rw to php_data:/var/www/html:rw, and also add php_data to the volumes: list as well? — J. Scott Elblein
@J.ScottElblein Your suggestion made it run, but can't be accessed through localhost:8080 and it keeps restarting when I docker ps. — alvirbismonte

src should be a directory containing your web content, not a file.
